Q.
Nature of equipotential surface for a point charge is
KCETKCET 2016Electrostatic Potential and Capacitance
Solution:
Electric potential due to point charge is given by the formula
$V=\frac{k q}{r}$
As, all the points on equipotential surface will be equidistance from the charge.
Hence, it is spherical symmetry.
