ICS Part 2 Physics Chapter 12 Short Questions Preparation

Question # 1

If a point charge q of mass is released in a non-uniform electric field with field lines pointing in the same directions,will it make rectilinear motion?

Ans 1: If a point charge q of mass m is placed at any point in the field ,it will follow straight or rectilinear path along the field line due to repulsive force.

Question # 2

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 # 3

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 # 4

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 # 5

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 # 6

Center of planetary system is oppositely charged to the rest of planets.How orbits of planets would be modified?

Ans 1: It would add or subtract the gravitational force if the charge was ;large enough and the sun was charged.So the radius of the orbits would be changed

Question # 7

A point charge move rectilinear path in an electric field.Explain.

Ans 1: If a point charge q of mass m is placed at any point in the field in the point,it will follow straight or rectilinear path along the field line due to repulsive force.

Question # 8

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 # 9

State coulomb's law.

Ans 1: It states that the force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charge and inversely proportional to the square of the distance between them.

Question # 10

Does the total flux depend upon the shape or geometry of the closed surface?

Ans 1: No,the total flux does not depend upon the shape or geometry of the closed surface,It depends upon medium and charge enclosed.
