1. One Mark Questions

1. The unit of charge is Coulumb

2. The value of "Eo" is 8.854X10-12

3. Electric potential is quantity Scalar

4. The electric lines start from……….to………………..

5. Torque experienced by on electric dipole in the uniform electric field t =p x E (vector)

6. If the point 'p' lies on the equatorial line of the dipole, then 0= 90°, Hence "V" = 0

7. What is polarization?

8. The value of IMF is?

9. What is action of point?

10. The SI unit of capacitance is? Farad

II. Very Short Answer.

1. State coulomb's law

2. Define electic dipole.

3. Define Equi- potential ace

4. What is electric flux?

5. Write Gauss law

Gauss law: Gauss’s law states that if a charge Q is enclosed by an arbitrary closed surface, then the total electric flux ΦE through the closed surface is

ΦE = ∮E⃗  .d A⃗  = Qendε0

A positive point charge Q is surrounded by an imaginary sphere of radius r as shown in figure. We can calculate the total electric flux through the closed surface of the sphere using the equation.



III. Short Answer

1. Verify coulomb's law

2. Write the properties of electric lines of force.

3. Derive Electric potential due to a point charge

4. Explain the energy stored in the capacitor.

5. Write the application of capacitors.



IV. Write in detail.

1. Derive the Electric field due to an electric dipole at point of the axial line.
