Find force F required to keep the system...

Find force F required to keep the system in equilibrium. The dimensions of the system are `d = 0.3 m` and `a = 0.2 m`. Assume the rods to be massless.

A

`150(hati)`

B

`150(-hatk)`

C

`150(-hati)`

D

it cannot be in equilibrium

Text Solution

Verified by Experts

The correct Answer is:
C
Net torque about `C` is zero
`Fa+100x=0`
`F=-100d/a=-150`
`vecF=-150hati`
