ICS Part 2 Physics Chapter 12 Short Questions Preparation

Question # 1

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 # 2

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 # 3

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 # 4

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 # 5

Is it true that Gauss's law states that the total number of lines of forces crossing any closed surface in the outwards direction is proportional to the net positive charged enclosed within surface?

Ans 1: Yes the above statement is true,The total number of lines of force crossing any close surface in the outwards directions means electric flux.

Question # 6

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 # 7

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 # 8

Define Time constant for RC Circuit.

Ans 1: The time required by the capacitor to deposit 0.63 times the equilibrium charge q is called time constant.The product of R and C has the dimensions of time.So this product is known as time constant.
t=RC

Question # 9

What depend on the slow or fast charging and discharging of a capacitor?

Ans 1: How fast or how slow the capacitor is charging or discharging depends upon the products of the resistance and the capacitance called time constant.Capacitor is charged or discharged rapidly when RC is small.

Question # 10

What is the effect of medium between the charges upon coulomb's force?

Ans 1: .If an insulating material i.e direction is places between the charges ,it will reduce the electrostatic force as compared to free space by factor called relative permittivity.
