1.	A small object of uniform density rolls up a curved surface with an initial velocity `v`. It reaches up to a maximum height of `(3v^(2))/(4g)` with respect to the initial position. The object is (a). Ring (b). solid sphere (c). hollow sphere (d). disc
Answer» `(1)/(2)mv^(2)+(1)/(2)I((v)/(R))^(2)=mg((3v^(2))/(4g))` `thereforeI=(1)/(2)mR^(2)` `therefore` body is disc The correct option is (d).
