Two bodies A and B of masses `10 kg and 5 kg` placed very slightly seperated as shown in figure The coefficient of friction between the floor and the block are as `mu_(s) = 0.4` block A is pushed by an external force F The value of F can be changed when the weight between block A and ground breaks block A will start pressing block B will start pressing the vertical wall

The force of friction acting on B verius with the applied force F acceleration to curve

Text Solution

Verified by Experts

The correct Answer is:

Unill the `10 kg` block is sticked with ground `(F = 40 N`) force will be felt `5 -kg` block .After `F =60N` and after that the kinetic friction start acting on `5kg` block which will be come `(20 N)`
