Consider the arrangement shown in figure. Friction coefficient for all the surfaces are shown in the figure and the rod connecting two upper blocks is horizontal.

What is the minimum value `F` so that the rear two blocks start sliding with each other `:`

A

`100N`

B

`50N`

C

`150N`

D

For all values of `F` both the rear blocks will move together

Text Solution

Verified by Experts

The correct Answer is:
D
Given system can accelerate in rightward direction

`f_(2) lt f_(1)` so all three blocks `A,B,C` will move with same acceleration for all value of `F`.
