JEE Main 2025 Physics question
A block of mass 25 kg is pulled along a horizontal surface by a force at an angle 45° with the horizontal. The friction coefficient between the block and the surface is 0.25. The block travels at a uniform velocity. The work done by the applied force during a displacement of 5 m of the block is :
Answer: (4)
Solution
Force balance: . Solving gives . Work J.
