The solid cylinder and a hollow cylinder, both of the same mass and same external diameter are released from the same height at the same time on a inclined plane. Both roll down without slipping. Which one will reach the bottom first?
Options
- ABoth together only when angle of inclination of plane is
- BBoth together
- CHollow cylinder
- DSolid cylinder
Correct answer
B. Both together
Step-by-step solution
\mathrm{t}=\frac{1}{\sin \theta} \sqrt{\frac{2 \mathrm{~h}}{\mathrm{~g}}\left(1+\frac{\mathrm{k}^2}{\mathrm{R}^2}\right)}
If a solid and hollow body of same shape are allowed to roll down on inclined plane then as , solid body will reach the bottom first with greater velocity.
