A sphere starts roling down can incline of inclination theta. Find the speed of its centre whenit has covered a distance l.

Text Solution

Verified by Experts

The correct Answer is:
A
A sphere is rolling in an inclined plane with incliN/Ation `theta` therfore according to the principle
` _gt mglsintheta=1/2Iomega^2+1/2mmv^2`
`rarr 1/2xx2/5mv^2+1/2mv^2=7/10`
`rarr gl sintheta=7/10v^2`
`rarr v=sqrt((10/7 glsintheta))`
