Question

A horizontal force of 10 N is necessary to just hold a block stationary against a wall. The coefficient of friction between the block and the wall is 0.2. The weight of the block is (A) 20 N (B) 50 N (C) 100 N (D) 2 N

Tardigrade Admin · Accepted Answer

Weight of the block = μR = 0.2 × 10 = 2N.

Q. A horizontal force of $10 N$ is necessary to just hold a block stationary against a wall. The coefficient of friction between the block and the wall is $0.2$ . The weight of the block is

$20 N$

$50 N$

$100 N$

$2 N$

Weight of the block $= μ R = 0.2 \times 10 = 2 N .$
