Assertion: Torque on a body can be zero event if there is a net forces on it. Reason: Torque and force on a body are always perpendicular.

Question

Assertion: Torque on a body can be zero event if there is a net forces on it. Reason: Torque and force on a body are always perpendicular. (A) If both assertion and reason are true and reason is the correct explanation of assertion (B) If both assertion and reason are true but reason is not the correct explanation of assertion (C) If assertion is true but reason is false (D) If both assertion and reason are false

T = r × F Torque is always perpendicular to radius vector and Force vector. If only one force is acting on body and we calculate torque about the point of action of force the torque is zero beginarrayc ⇒ text when &gamma;=0, F ≠ 0 T =0 endarray
