Question

what is the work done in moving a test charge q through a distance of 1cm along the equatorial axis of an electric dipole​

Answer 1

Answer:

At every point on equatorial axis, the potential is zero, so work done W = qΔV = 0(zero).

Explanation:

i tnk this is the answer.

if correct plz make me Brainlist..

Answer 2

Answer:

Work done is given by,

W = qV

Since, the equitorial plane is also equipotential, we have,

Veq=0

Therefore, work done in moving a positive test charge q through a distance of 1 cm is,

W=0
