Question

A charge of -100e is kept at a point and a point charge of +10e is moved once around it in a circular path of radius r .The work function isA charge of -100e is kept at a point and a point charge of +10e is moved once around it in a circular path of radius r .The work function is

Answer 1

Answer:

the work done to revolve the charge must be ZERO

Explanation:

As we know that the charge q = -100e is fixed at the center while the other charge Q = +10 e is moved around it in the circle

Now we know that work done to move the charge from one point to other point is given as

$W = Q(V_2 - V_1)$

here we know that

$V_2 - V_1$ = potential difference of two points

since the charge is revolved around in circle so here the potential difference of two points must be ZERO

so the work done to revolve the charge must be ZERO
