A weightless rod is acted upon by upward parallel forces of 2N and 4N at ends A and B respectively. The total length of the rod AB=3 m. To keep the rod in equilibrium, a force of 6N should act in the following manner

A

Downward at any point between A and B

B

Downward at mid point of AB

C

Downward at a point C such that AC=1 m

D

Downward at a point D such that BD=1 m

Text Solution

Verified by Experts

The correct Answer is:
D
force 6N is applied in such a way that the torque about any point on rod should be zero.
