a block of mass 200 kg is kept on a rough horizontal surface. It just begins to move when a force of 200 kg wt. is applied .calculate the coefficient of static friction.

Question

Arun · Answer

Dear Rudra

Mass = 200 kg.

Force = 200 N.

Coefficient of static friction = ( ? )

It means we need to calculate how much resistance to friction the block is on the rough surface.

So Friction = Coefficient of static friction × Mass × Gravitational Acceleration

200 = 200 × 10 × coefficient of static friction

200 / 2000 = Coefficient of static friction

Coefficient of static friction = 0.1
