A coin is placed on a rotating turning table slips if placed at minimu

1.	A coin is placed on a rotating turning table slips if placed at minimum dist of 9cm from centre if angular velocity of turn table is tripled
Answer» ANSWER: Explanation: (w= angular VELOCITY) F= m w^2 r F slip= m w^2 40. --> EQN(1) F slip= m (2w)^2 R2 F slip=4m w^2 R2 --> eqn(2) solving 1 and 2 m w^2 40 = 4 m w^2 R2 so R2 = 10 cm

Answer»

ANSWER:

Explanation:

(w= angular VELOCITY)

F= m w^2 r

F slip= m w^2 40. --> EQN(1)

F slip= m (2w)^2 R2

F slip=4m w^2 R2 --> eqn(2)

solving 1 and 2

m w^2 40 = 4 m w^2 R2

so R2 = 10 cm
