The Internet has many places to ask questions about anything imaginable and find past answers on almost everything.

## What will happen if a charged object is brought close to a neutral object?

In the induction process, a charged object is brought near but not touched to a neutral conducting object. The presence of a charged object near a neutral conductor will force (or induce) electrons within the conductor to move. The flow of electrons results in a permanent charge being left upon the object.

## What happens when a charged object touches a neutral object?

When a charged object is used to charge a neutral object by conduction, the previously neutral object acquires the same type of charge as the charged object. The charge object maintains the same type of charge that it originally had. So in this case, both objects have a negative charge.

## What is happening when a negatively charged rod becomes grounded?

Positively charged objects have more protons than electrons. A negatively charged object has more electrons than protons. When a negatively charged rod becomes grounded, it becomes neutral.

## Can 2 like charges attract each other?

Yes, this is possible. But as we know that like charged body repels each other whereas unlike charged body attracts attracts each other is not false. induced charge on the other exceeds the force of repulsion between q 1 and q 2 . Hence there is only one case when like charged body attract each other.

## What happens when 2 objects are rubbed together?

When two different materials are rubbed together, there is a transfer of electrons from one material to the other material. This causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer).

## Is an attractive force positive or negative?

In general when the force is attractive, the potential energy is negative and as shown above force will be negative. In case of repulsion, with the same argument, the force will be positive.

## How do you tell if a force is repulsive or attractive?

If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive. This called Coulomb’s law and was the first attempt to understand the electric force. Like the gravitational force, the Coulomb force is an inverse square law.

## What is an attractive force?

attractive force – the force by which one object attracts another. attraction. affinity – (immunology) the attraction between an antigen and an antibody. bond, chemical bond – an electrical force linking atoms.

## Why is attractive energy negative?

A trapped particle (trapped by an attractive force) requires energy to be freed, hence describing it as having negative potential energy. Another way to think of it is that an attractive force causes the distance between two bodies to shrink, and their relative velocities are becoming increasingly negative.

## Is negative force attractive?

Of course, the gravitational force is always attractive, so this minus sign is always present, but in different kind of forces such as Coulomb force, a negative module means an attractive force while a positive module means a repulsive one, and the sign of the module comes from the sign of the charges.

## How can we attract positive energy from the universe?

Here are 7 ways to be the energy you want to attract

1. Rein in your thoughts. Like everything else, your thoughts and feelings also are energy vibrations.
2. Break away from negative influences.
3. Realize your worth.
4. Balance the energies.
5. Learn to forget and forgive.
6. Start your day on a positive note.
7. Be patient.

## Which force is always negative in sign?

gravitational force

## Can the Force be negative?

It can negative. it means that the force is going to the opposite direction. So force A must be acting downwards, not upwards. A ‘negative’ force is one that is acting in the direction opposite to what you decide to be the positive direction (Usually, upward is +ve, downward is -ve).

## In which case is negative work done?

Negative work follows when the force has a component opposite or against the displacement. Negative work removes or dissipates energy from the system. Two examples: In pulling a box of books along a rough floor at constant velocity, I do positive work on the box, that is I put energy into the system.

## Can the normal force be negative?

The normal reaction force is the force the ground exerts on the object to prevent the object from sinking into the ground. In which case, it would means that the object is floating just above the surface, not really touching it. But it cannot be negative.

## What is normal force equal to?

This supporting force acts perpendicular to and away from the surface. It is called a normal force, and it also goes by the name “apparent weight.” When objects rest on a non-accelerating horizontal surface, the magnitude of the normal force is equal to the weight of the object: N=mg.

## Why is normal force less than weight on an incline?

The normal force is always perpendicular to the surface, and since there is no motion perpendicular to the surface, the normal force should equal the component of the skier’s weight perpendicular to the slope.
