Question

Can two equipotential surfaces intersect
each other? Give reasons.
Two charges + q and -9 are located at
points A(0, 0, - 2) and B(0, 0, 2)
respectively. How much work will be done
in moving a test charge from point P (0,0,0)
to Q (-5, 0, 0)?
​

Answer 1

On an equipotential surface , the potential difference between any two points is zero. ... Now since the electric field is perpendicular to the equipotential surface ,their intersection means that there are two directions of the electric field at their intersection point which is not possible.

Hope thse helps u to understand my ans

Answer 2

$\mathfrak{\huge{\red{ANSWER}}}$

i) No  Reason: At the point of intersection, there will be two different directions of electric field, which is not possible. 

(ii) Work done in moving test charge atom P to Q is zero. Reason: Test charge is moved along the equatorial line of an electric dipole.

Potential at every point on equatorial line is zero
