Questions + Answers key
Take MCQ Physics Test1.
Define ‘capacitance’. Give its unit.
2.
What is polarisation?
3.
What is meant by electrostatic energy density?
4.
Define ‘electrostatic potential energy’.
5.
What are the properties of an equipotential surface?
1.
The capacitance C of a capacitor is defined as the ratio of the magnitude of charge on either of the conductor plates to the potential difference existing between the conductors. \(C=\frac{Q}{V}\)
Its unit is Coulomb per volt or farad (F).
2.
The alignment of the dipole moments of the permanent or induced dipoles in the direction of applied electric field is called polarisation.
3.
The electrostatic energy stored per unit volume of space is called electrostatic energy density.
\(u_E=\frac{1}{2}ε_0E^2\)
4.
Electrostatic potential energy is the work done to assemble the charges at the given locations brought from infinity. If q1 and q2 are the charges to be assembled with a separation of distance r, the electric potential energy is, \(U=\frac{1}{4\piε_o}\frac{q_1q_2}{r}\)
5.
(i) The work done to move a charge q between any two points A and B, W = q (VB - VA). If the points A and B lie on the same equipotential surface, work done is zero because VB = VA.
(ii) The electric field is normal to an equipotential surface.
