In previous problem, what is the reaction force on the hinge ?

A

`W - P` upward

B

`W - P` downward

C

`W - P` to the left

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
(b) `R + P = W rArr R = W - P`
This is the reaction on rod upward direction, so from third law, reaction on hinge will be `R` in downward direction.
