# Masses on Turntable

SATPHY-GYQYWE

A blue cylinder and a green cylinder are on a horizontal turntable that is spinning counter-clockwise as seen from above.

The blue cylinder and the green cylinder are identical in most every respect except for their colors and masses (The blue one is taller to give it more mass.). The blue cylinder is twice as massive as the green cylinder.

The cylinders are located the same distance from the center of the turntable, as pictured below. When the turntable spins fast enough, the green mass slides off.

How many times as fast (compared to the speed at which the green mass slides off) must the turntable spin to cause the blue mass to slide off?

A

The blue mass will slide off at the same speed as the green one will.

B

2 times as fast

C

3 times as fast

D

4 times as fast

E

The blue mass will slide off at a slower speed than the green one.
