·       Unit - 1.

PART - A

 

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

PART - B

 

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.

PART - C

 

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.

 

PART-D

IV. Write in detail.

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