Answer:
Zero
Explanation:
Work done will be zero.
Becuase Displacement and Force are perpendicular to each other.
Hence angle forms is 90
W = F S cos(theta)
W = F S cos(90)
W = F S (0). cos90 is 0
Hence work done is Zero

Answer:
0
Explanation:
Work done = Force* displacement
Here nothing is moving i.e. ni displacement takes place, so, Displacement = 0
Hence, Work Done = Force*0
Work Done = 0
