On the horizontal surface of a truck `(mu=0.6)` a block of mass 1 kg is placed. If the truck is accelerating at the rate of `5m//sec^(2)` then friction force on the block will be

On the horizontal surface of a truck, a block of mass 1 kg is placed (mu = 0.6) and truck is moving with acceleration with 5 m//s then the frictional force on the block will be:

On horizontal surface of a truck a block of mass 1 kg is placed (mu = 0.5) and truck is moving with acceleration 5 ms^-2 , then frictional force on block will be

On the horizontal surface of plank a block of mass 1 kg is placed (mu=0.6) which is stationary w.r.t. plank. Plank is moving with acceleration 5 m//s^(2) , then the frictional force on the block will be

A block of mass 1kg lies on a horizontal surface in the truck, the coefficient of friction between the block and the surface is 0.6. If the acceleration of the truck is 5ms^(-2) the frictional force acting on the block is

A block of mass 1kg lies on a horizontal surface in a truck. The coefficeint of friction between the block and surface is 0.5. If the acceleration of the truck is 6ms^(-2) the acceleration of the block relative to ground is
