Compute the minimum torque must be applied to second hand

Reference no: EM13332255

A clock has a second hand whose tip rubs against the inside of the glass cover. If the frictional force between the glass cover and the tip of the second hand is 0.0036 N and the length of the hand is 10.0 cm, what is the minimum torque that must be applied to the second hand if the clock is not to be stopped?
