The minimum value of mu between the two ...

The minimum value of `mu` between the two blocks for no slipping is

A

`(F)/(mg)`

B

`(F)/(3 mg)`

C

`(2 F)/(3 mg)`

D

`(4 F)/(3 mg)`

Text Solution

Verified by Experts

The correct Answer is:
C
If they do slip, then not force on system `= F`
`:.` Acceleration of system `a = (F)/(3m)`
`T = F`
`FBD` of `m F - mu mg = ma = (F)/(3)`

`:.mu mg = (2 F)/(3)` or `mu = (2 F)/(3 mg)`
