In the question, in which direction the net torque on the pulley will act? (M1 > M2)
Two forces F1=5 N and F2=8 N acting at points A and B on a rod pivoted at a point O, such that OA = 2 m and OB = 4 m. Calculate the net torque of the two forces about O.
Two long wires AB and CD carry currents i1 and i2 in the direction shown in figure.
