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 prssing block B will start pressing the vertical wall

If `F = 50N `the friction force acting between block B and ground will be

`10N`

`20N`

`30N`

None

Text Solution

Verified by Experts

The correct Answer is:

If `F=50N`, form on `5kg` block `=10N`

So friction force `=10N`
