In front of a uniformly charged infinite non-conducting sheet of surface charge density σ, a point charge q 0 is shifted slowly from a distance a to b (b > a). If work done by external agent is W, then find out relation between the given parameters.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
= – 
(b – a)
Sol.
W ext = q 0 (V B – V A ) = q 0 
;
∴ W ext = q 0 
= 
(a – b)
