Question

Two uniform solid spheres having unequal masses and unequal radii are released from rest from the same height on a rough incline. If the spheres roll without slipping:

• A. the heavier sphere reaches the bottom first
• B. the bigger sphere reaches the bottom first
• C. the two spheres reach the bottom together
• D. the information given is not sufficient to tell which sphere will reach the bottom first.

Answer 1

The correct option is C the two spheres reach the bottom together

As both the bodies are solid sphere their acceleration is equal as they have some ratio of $\left(\frac{K}{R}\right)$ and gravitational acceleration is same.

$\therefore$ They reach the bottm together.
