Answer :

Given,


Charge at origin (O), q0 = 8 × 10-3 C


The charge (q1 = -2 Nc) is moving through the given points, P(0, 0, 3)cm, R(0, 6, 9)cm and Q(0, 4, 0)cm respectively.


The picture below represents above situation,



Since, Work is independent on the path followed we concentrate on point P and Q only.


Potential at any point is given by,


Where,


q = charge


d = distance from origin


ϵ0 = permittivity of space


and,


Thus, Potential at point P,


( distance of point from origin = 3 cm = 0.03m)


Potential at point Q,


Work done, W = q1 × (Change in potential difference)





= 1.27 J
