Question

Blocks are at rest & pulled by F & F', find tension force in the string

• A. T=13 N
• B. T=23 N
• C. T=0 N
• D. T=18 N

Answer 1

The correct option is C T=0 N

First find the limiting friction $\mu$N for both the blocks. It comes out to be 6 and 20 newton respectively. Applied force is lesser than friction for both therefore blocks won't move for T < 5 N. Hence T=0.
