## Which experiment will you perform to prove that electrostatic force is a non contact force?

General Science ➡Take a comb rub it with ur hard and take small piece of paper and now move it near the comb u will see that the comb attarcts the papers this proves that electrostatic force is non contact force ……!!!!

What is electrostatic force Why is it called a non-contact force?

Electrostatic forces are non-contact forces; they pull or push on objects without touching them. Rubbing some materials together can result in something called ‘charge’ being moved from one surface to the other. Charged objects pull on other uncharged objects and may either push or pull on other charged objects.

### What is electrostatic force give a simple activity to observe its effect?

When the comb is rubbed in your dry hair, it acquires a property called electrostatic charge. Electrostatic charge can exert a force called electrostatic force. It is because of this force that the bits of paper gets attracted to your comb.

Is friction a non-contact force?

Non-contact force occurs due to either attraction or repulsion between two objects such that there is no contact between these objects. The frictional force is an example of a contact force. Gravitational force is an example of a non-contact force.

#### How will you prove that static electricity force is a non-contact force?

If another charged object is moved into the electric field, a force acts on it. The force is a non-contact force because the charged objects do not have to touch for the force to be exerted.

As you remove your hat, electrons are transferred from hat to hair, creating that interesting hairdo! Remember, objects with the same charge repel each other. Because they have the same charge, your hair will stand on end. Your hairs are simply trying to get as far away from each other as possible!

## What are the non contact forces give two examples?

Some of the examples of non-contact forces are:

• Gravitational force.
• magnetic force.
• Electrostatics.
• The nuclear force – (there are two types of strong and weak nuclear force).

Which is an example of a non-directional force?

As you know, it’s going to attract all the iron pieces around it, no matter what will be the direction of force. So, these forces are non directional forces, as it doesn’t act in a specific direction and hence the ionic bond so formed between Na+ and Cl- is a non -directional bond.

### Is the electrostatic force a contact or non contact force?

A central idea for students to understand is that electrostatic forces are non-contact forces; it is not important at this level to emphasise to students that ‘like charges repel and unlike charges attract’.

Which is an example of non-directional bonding?

Non-directional bonding is the bonding which involves opposite charges such as metallic and ionic. For instance, a metal cation in a metallic lattice will attract electrons from all directions with a uniform force, and these electrons can move and the force of attraction will remain the same,…

#### How are divergences used in electrostatics experiments?

Their divergence indicated the presence of charge. A modern electroscope such as the one used in your experiments consists of a fixed insulated vane, to which is attached a delicately balanced movable vane or needle. When charge is brought near the top electrode, the movable vane moves outward, being repelled by the fixed vane.
