Answer:
Only if it starts moving
Explanation:
Work done is defines as
In two case work done will be zero
First case is that when force and displacement are perpendicular to each other
What’s more, other case is that when there is no displacement
So for work to be done there must have displacement, in the event that there is no displacement then there is no work done
