Question

A bottle of mass 0.3 kg sits on a rotating platter. The bottle follows a circular path of radius 0.3 m at a speed of 0.6 m/s. What is the centripetal force on the bottle?

 		A.	1.2 N
 		B.	0.6 N

 		D.	0.9 N

anonymous · Answer

Centripetal force is given by:$$F _{c}=\frac{ mv ^{2} }{ r }$$where Fc is centripetal force; m is mass; v is velocity; and r is the radius of the circle of motion.  This should allow you to find the correct answer.
