A rigid rod of length 2L is acted upon by some forces. All forces labelled F have the same magnitude. Which cases have a non-zero net torque acting on the rod about its centre?
Text Solution
Verified by ExpertsThe correct answer is:
A
By sign convention anticlockwise moment (or torque) is taken as positive while clockwise moment (or torque) is taken as negative.
In case I, net torque about its centre is
In case II, net torque about its centre is
In case III, net torque about its centre is
