A solid sphere and a solid cylinder having the same mass and radius, rolls down the same incline. The ratio of their acceleration will be

A

`15:14`

B

`14:15`

C

`5:7`

D

`7:5`

Text Solution

Verified by Experts

The correct Answer is:
B
`(a_(s.cy))/(a_(s.sph)) = ((1+(K^(2))/(r^(2))) _(s.sph))/((1+(K^(2))/(r^(2)))_(s.cy)) = ((1+2/5)/(1+1/2)) = 14/15`
