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
Full Answer Key Update Soon...........
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.
