ICS Part 2 Physics Chapter 12 Short Questions Preparation

Question # 1

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

Ans 1: For the identification of positively charged plate of a capacitor golf leaf electroscope is used,For this purpose the plate of capacitor is brought near the positively charged disc of electroscope.If the divergence of the gold leaves increase then the capacitor will be positively charged and vice versa.

Question # 2

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 # 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

What is Potential Gradient?

Ans 1: The quantity gives the maximum value of rate of change of electric potential in magnitude and direction with respect to distance,It is known as potential gradient.

Question # 5

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 # 6

Define xerography and photoconductor.

Ans 1: Xerograph is a photocopying process,It is taken from the Greek word "xeros" and "graphos" when mean dry writing.
Photoconductor is an insulator in the dark and becomes a conductor when exposed to light.

Question # 7

Write two properties of electric field.

Ans 1: 1.Electric field line originate from positive charge and end om negative charges.
2.The tangent to a field line at any point gives the direction of the electric field intensity at the point.

Question # 8

Write down two difference between electric and gravitational force.

Ans 1: Differences:Electrical force is might be attractive as well as repulsive while the gravitational force is only attractive.Electrostatics force is medium dependent while the gravitational force is not.

Question # 9

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 # 10

Define electric flux.Write its SI units.

Ans 1: The number of the field lines passing through a certain element of area is known as electric flux through that area.Its SI units is Nm²C^-1.
