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 = 20N`,with how much force block A press block B?

A

`10N`

B

`20N`

C

`30N`

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
D
If `F=20N, 10 kg` block will not move and it would not press `5kg` and So `N=0` .
