If the coefficient of friction between ...

If the coefficient of friction between all surface figure is `0.4` then find the minimum force `F` to have equilibrium of the system.

A

32.5 N

B

150 N

C

135 N

D

50 N

Text Solution

Verified by Experts

The correct Answer is:
A

(a) `2T=250`

`therefore" " T=125N implies T+0.4F=150`
`therefore" " F=62.5N`
