In given diagram what is the minimum value of a horizontal external force F on block A so that block B will slide on ground is .

A

`30N`

B

`20N`

C

`10N`

D

Not possible

Text Solution

Verified by Experts

The correct Answer is:
D

`F_(1(max))=0.2xx10xx10=20N`
`F_(2(max))=0.1xx30xx10=30N`
`F_(1(max))lt F_(2(max))`
`rArr 'B'` can never move.
