Question

A block of mass 0.1 kg is held against a wall by applying a horizontal force of 5 N on the block. If the coefficient of friction between the block and the wall is 0.5, the magnitude of the frictional force acting on the block is (A) 2.5 N (B) 0.98 N (C) 4.9 N (D) 0.49 N

Tardigrade Admin · Accepted Answer

∴ Block is stationary so f=0.98 N

Q. A block of mass $0.1 k g$ is held against a wall by applying a horizontal force of $5 N$ on the block. If the coefficient of friction between the block and the wall is $0.5$ , the magnitude of the frictional force acting on the block is

2.5 N

0.98 N

4.9 N

0.49 N

$∴$ Block is stationary so $f = 0.98 N$
