[" 1) surface of plank a block of mass "1kg" is placed "(mu=0.6)" when the block will "],[[" (B) "6N," (D) "8N]]

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

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 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 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 (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 (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
