Question
The work done on a particle of mass m by a force, 
(K being a constant of appropriate dimensions), when the particle is taken from the point (a, 0) to the point (0, a) along a circular path of radius a about the origin in the x-y plane is :-
(K being a constant of appropriate dimensions), when the particle is taken from the point (a, 0) to the point (0, a) along a circular path of radius a about the origin in the x-y plane is :-Options
A.
B.
C.
D.0
Solution
Particle is moving in x-y plane so
Force is radial so work done by this force in closed loop = 0
Force is radial so work done by this force in closed loop = 0
