Question

Consider two spheres A (solid sphere) and B (hollow sphere) each of radius \(R\), kept on a perfectly rough surface. Mass of sphere A is 5 m and that of B is 2 m. If the same force \(F\) is applied at the top tangentially, then find the ratio of acceleration of A to acceleration of B.

• A. \(\frac{5}{17}\)
• B. \(\frac{10}{21}\)
• C. \(\frac{3}{5}\)
• D. \(\frac{2}{7}\)

Hint:

In problems involving rolling motion, use the relationship \(a = R \alpha\) and consider the moments of inertia for different objects (solid sphere or hollow sphere) to find the accelerations.

Answer 1

The Correct Option is B
