A force 
(where K is a positive constant) acts on a particle moving in the x-y plane. Starting from the origin, the particle is taken along the positive x- axis to the point (a, 0) and then parallel to the y-axis to the point (a, a). The total work done by the forces 
on the particle is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
For motion of the particle from (0, 0) to (a, 0)
Displacement 
So work done from (0, 0) to (a, 0) is given by
For motion (a, 0) to (a, a)
and displacement
So work done from (a, 0) to (a, a) 
So total work done
