Question

A block of weight 20 N is pressed against a wall by applying a horizontal force of the block (g=10 m/s) if coefficient of friction is 0.4 then, the least horizontal force required to keep the block in equilibrium is

Answer 1

Answer:

A block of weight 20 N is pressed against a vertical wall as shown in figure by applying a horizontal force of the block (g = 10 ms?). If coefficient of kinetic friction = 0.4 then

The least horizontal force required to keep the block in rest is

a) 40 N

b) 20 N

c) 10 N

d) 50 N
