Q1.Two identical point charges
of magnitude –q are fixed as shown in the figure below. A third charge +q is
placed midway between the two charges at the point P. Suppose this charge +q is
displaced a small distance from the point P in the directions indicated by the
arrows, in which direction(s) will +q be stable with respect to the
displacement?

Q4.An electric dipole is
placed at an alignment angle of 30º with an electric field of 2 × 10^{5}
N C^{-1}. It experiences a torque equal to 8 N m. The charge on the
dipole if the dipole length is 1 cm is

Q5.Four Gaussian surfaces are
given below with charges inside each Gaussian surface. Rank the electric flux
through each Gaussian surface in increasing order.

Q7.Two identical conducting
balls having positive charges q_{1} and q_{2} are separated by
a center to center distance r. If they are made to touch each other and then
separated to the same distance, the force between them will be

Q9.An electric field exists in a certain region
of space. Then the potential difference V = V_{o} – V_{A},
where V_{o} is the potential at the origin and V_{A} is the
potential at x = 2 m is:
