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

30 N

B

20 N

C

10 N

D

not possible

Text Solution

Verified by Experts

The correct Answer is:
D

`F_(1(max))=0.2xx10xx10=20N`
`F_2=0.1xx30xx10=30N`
`F_(1(max))ltF_(2(max))`
`implies`B can never move.
