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 wall is μ The weight of the block is

Answer 1

ANSWER
_____________________________

Maximum friction (f) = μ × N
=> f = 10 N × μ

=> f = (10 μ) N

In equilibrium I.e. block is held stationary against wall

f = mg

=> mg = ( 10 μ ) N

=> Weight = ( 10 μ ) N
