ICS Part 2 Physics Chapter 12 Short Questions Preparation

Question # 1

Suggest a method 'shield' an apparatus from electric field even when it is to be kept in the region where electric field is present.

Ans 1: An apparatus will be shielded from electric field when it is kept inside the metallic box,so that the charge will only reside on the outer surface of the container.It is in accordance with Gauss law.

Question # 2

What is electric potential energy and electric potential difference?

Ans 1: Electric potential energy: The energy is acquired by unit positive charge in carrying it from one point to the other against the electric field keeping it in electrostatic equilibrium is called as electric potential energy,It is the energy stored in the charge 'q' because of its position in an electric field.It is measured in joules.
Ans 2: Electrical potential difference: The electric potential difference between two points is defined as the work done in carrying a unit a positive charge from one point to other point while keeping the charge in electrostatic equilibrium.

Question # 3

What is capacitor?Define the capacitance.

Ans 1: Capacitor is a device used to store charge,
Capacitance is a measure of ability of capacitor to store charge.

Question # 4

Define electrostatics and electric force,

Ans 1: Electrostatics: The branch of physics which deals with the study of stationary charges is called electrostatics.Electric force: The force which holds the negative and positive charges that make up atoms or molecule is called electric force.

Question # 5

Why do the electrons tend to go to region of high potential?

Ans 1: We know that the electrons are negatively charged particles.So,when they are put inside an electric field they tend to go the region of high potential from the region of low potential.

Question # 6

Define electric polarization and electric dipole.

Ans 1: When dielectric is placed between the plants of capacitor,positive and negative charge of its molecules displace from their position.Positive charges are attracted towards negative plates and negative charges towards positive plate,dipoles are formed.This process is called polarization.
Two equal and opposite charges separated by a small distance is called dipole.

Question # 7

Define electric intensity and give its unit.

Ans 1: The electrostatic force per unit test charge,at a specific point in the electric field is called electric field intensity.Its unit is NC^-1.

Question # 8

Is E is necessary zero inside a charged rubber balloon if balloon is spherical?

Ans 1: Yes, E is necessarily zero inside a charged rubber balloon if balloon is spherical.

Question # 9

Do electrons tend to go region of high potential or low potential?

Ans 1: Electrons tend to go to a region of high potential from low potential because electrons are negatively charged.

Question # 10

How can you identify that which plate of a capacitor is positively charged?

Ans 1: Gold leaf electroscope is used,To check the polarity,disc of positively charged electroscope is brought close to the capacitor plate.If the divergence of gold leaves increases;the plate is positively charged and vice versa.
