Electric field lines
The above diagram shows the lines of electric force and equipotential lines on a particular plane. Which of the following statements is correct?
a) The electric potential at point
A
is higher than that at point
B
.
b) The electric field strength at point
A
is the same as that at point
B
.
c) The work done by the electric force when an electrically charged particle is moved from point
B
to
C
along the equipotential line is zero.

The work done in moving a charge on a equipotential surface is always zero Hence if we move the charged particle from B to C the work done will be zero. According to the mathematical representation of electric field "V= Kq/r" As the distance (r) increases the electric potential (V) will fall down . Here point A is near than that of the point B, so the potential at point A will be higher than that of B.
