A disc is placed on the ground. Friction coefficient is `mu`. What is the minimum force required to move the disc if it is applied at the topmost point?

Text Solution

Verified by Experts


Even a small force will produce torque about bommommost point. So the disc starts toppling about bottommost point and here toppling means motion.
