Find ratio of acceleration and angularr acceleration of com? If for the above diagram m=2kg and r=10 cm

A

a.`(1)/(5)`

B

b.`(1)/(10)`

C

c.`(1)/(15)`

D

d.`(1)/(20)`

Text Solution

Verified by Experts

The correct Answer is:
D
`a=(F)/(m)=(20)/(20)=10`
`tau=Iprop`
`20xx(1)/(10)=(1)/(z)xx2x(0.1)^(2)xxprop`
`prop=200`
`therefore(a)/(prop)=(10)/(200)=(1)/(20)`
