Question

Two cylindrical containers are placed on a turntable. canister A is empty; canister B contains lead shots. each canister is the same distance r from the centre and the coefficient of static friction is uniform. what happens when the speed of the turntable is increased?

a) only the lighter container slides outward off the turntable; the heavier one stays on.
b) only the heavier container slides outward off the turntable; the lighter one stays on.
c) both containers slide off the turntable at the same turntable speed.
d) the lighter container slides inwards.
e) the heavier container slides inwards. ​

Answer 1

c) both containers slide off the turntable at the same turntable speed.

Step-by-step explanation:

The greater the mass of the cylinder, the greater the centrifugal force acting on it. That makes up for the greater force needed to move the heavier cylinder.
