Solution

The correct option is D A – p,q,r B – p,q,r C – p,q,r D – p,q
A) v=2gh1+k2r2 , Hence v depends on the shape and size.

B) t= 2h(1+k2r2)gsin2θ, Hence t depends on the shape and size.

C) a=gsinθ(1+k2r2), Hence a depends on the shape and size.

D) f=mgsinθ1+r2k2, Hence f depends on shape, size and mass.
