Charge Q moves once in a circular path of radius R around a charge the work done is
Answers
Answer:
The work done in moving a charge Q which moves in circular path is ZERO
Explanation:
Work done on carrying a charge from one place to another on is zero.
As we know that work done is the product of Force and displacement.
Workdone = W= F S Cosθ
Force is along the radius and direction of displacement is perpendicular to it.
θ=0°
cos 90= 0
Work done = Fs Cos 90
= 0
Answer:
zero
note: work should be done when a charge, q is moved in such a way that the distance between Q and q will varies.
but along a circular path the distance of separation is radius ( constant for a circle) , therefore potential remains same at the surface ( at any point) and so the potential difference is 0 and so work done also 0.
