Electric Potential & Capacitance | MCQs-01

Four point charges -Q, -q, 2q and 2Q are placed, one at each corner of the square. The relation between Q and q for which the potential at the center of the square is zero is-

Assertion- Work done in moving a charge between any two points in a uniform electric field is independent of the path followed by the charge between these points.
Reason- Electrostatic forces are conservative forces.

Equipotential surfaces associated with an electric field, which is increasing in magnitude along the X-direction are-

Assertion- When charges are shared between any two bodies, no charge is really lost but some loss of energy does occur.
Reason- Some energy disappears in the form of heat, sparking etc

Three capacitors each of 4 μF are to be connected in such a way that the effective capacitance is 6 μF. This can be done by connecting them-

An electric field of 1000 Vm^-1 is applied to an electric dipole at an angle of 45°. The value of electric dipole moment is 10^-29 C m. What is the potential energy of the electric dipole?

An electric field E = (25î + 30ĵ) NC^-1 exists in a region of space. If the potential at the origin is taken to be zero, then the potential at x=2 m, y=2 m is-
