Question

A block of mass 10kg is moving on a rough surface as shown. The fictional force acting on block is

Answer 1

When a block of 10 kg is moving on a rough surface and the angle of inclination is 30, the force of static friction is 5 kg.wt

1 kg.wt means a force that is required to accelerate a mass of 1 kg with an acceleration of approximately 9.8 m/s2

here the friction force required to stop the block is mg*sin30

since mass is equal to 10 kg

force required = 10*g*sin30 newton

                       = 5*g newton

                       = 5 kg.wt      (since 1 kg.wt = 1*g newton, where g = 9.8 m/s2)
