IMPORTANT SHORT & VERY SHORT ANSWER QUESTIONS WITH ANSWERS

 CBSE Class 12 Physics Rapid Revision Question Bank Set C 1
An education isn't how much you have committed to memory, or even how much you know. It's being able to differentiate between what you know and what you don't.
 
Anatole France
 
1. Electrostatics
1.In a parallel plate capacitor the capacitance increases from 16μF to 80μF on introducing a dielectric medium between the plates. What is the dielectric constant of the medium ?
K = Cm/Ca = 80/16 = 5
 
2. The force between two point charges kept at a distance of r apart is F. If the same charges are kept in water at the same distance, how does the force between them change?
Fa/Fw = K , Fw/Fa = 1/K =1/81
 
3. Under what conditions The electric field intensity due to two point charges be zero at a point in the line joining the two charges but the point should not be between the charges ?
The two charges should be of opposite charges and they should have different magnitudes.
 
4. How much work is done in moving a 500μC of charge between two points on an equipotential surface at a potential of 4V?
Zero. Work done in moving a charge along an equi potential surface is zero .
 
5. Define dielectric field strength .
It is the maximum electric field strength a medium can withstand before break down.
 
6. Define equi potential surface. Can two equi potential surfaces intersect?
If all the points on a surface are at the same potential such a surface is equi potential surface. Two equi potential surfaces cannot intersect if they intersect , two electric field lines must intersect which is not possible.
 
7. If the plates of a parallel plate capacitor are connected to each other by a copper wire, what will happen?
The charge will flow from positive to negative plate and the capacitor will be discharged completely. So the energy stored is dissipated as heat energy.
 
8. The plates of a charged parallel plate capacitor are connected to a volt meter , what will be the effect of increasing the separation between the plates on the voltmeter reading? Voltmeter reading increases.
 
9. A very thin metal plate of thickness t << d is kept in the middle of a parallel plate capacitor .What will be the effect on the capacitance of the system?
No change in the capacitance.
 
10. A 12pF capacitor is connected to a 50V supply. Calculate the electrostatic energy stored in the capacitor.
U = ½ CV2 = 1.5 x10-8J
 
11. How does the electric field inside a dielectric change when it is placed in an external electric field?
It decreases as the induced electric field is opposite to the applied field. Net electric field decreases.
 
12.The energy stored in a a capacitor of capacitance C is U ,Express the charge Q stored in it in terms of C and U.
Q= √(2CU)
 
13. What is the function of dielectric in a capacitor?
It increases the capacitance by reducing the effective potential difference between the plates.
 
14. A hollow metal sphere of radius 5cm is charged such that the potential on its surface is 10V. what is the potential at the centre of the sphere?
10 V. Potential inside a hollow metal surface is equal to its potential on the surface.
 
15.Can there be a potential difference between two adjacent conductors carrying the same charge?
Yes , if their sizes are different.
 
16. What is the geometrical shape of equi potential surfaces due to a single isolated charge?
Spherical for q>0 and q<0.
 
17.Name a Physical quantity whose SI unit is i) J/C ii) J /m3 iii) Volt /m , State whether it is a scalar or vector quantity?
i) electric potential – scalar ii) energy density – scalar iii) electric field strength – vector
 
18.What is the dielectric constant of a metal?
Infinity , as the electric field inside a conductor (metal ) is zero
 
19.Why is the potential inside and on the surface of hollow conducting sphere same and remains constant?
dV = -E.dl since electric field inside the conductor is zero dV = 0 V is constant.
 
20. State the differences between electric potential at a point due to a single point charge and an electric dipole.
