A box of `20kg` mass is pulled by force F with constant velocity on a horizontal surface. If force of friction is 49 N, work done during displacement of 10m is………….J.

490

245

980

zero

Text Solution

Verified by Experts

The box moves with constant velocity, i.e., balanced forces are acting on it. The resultant force of balanced forces is zero. Hence, work being done during displacment of the box would be zero.
