Two bodies A and B of masses `10 kg and 5 kg` placed very slightly separated 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

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 = 50 N` force on `5kg` block`= 10N`

so friction force`= 10 N`
