A solid sphere of mass M and radius R is placed on a rough horizontal surface. It is pulled by a horizontal force F acting through its centre of mass as a result of which it begins to roll without slipping. Angular acceleration of the sphere can be expressed as:
- \(\frac{3 F}{4 M R}\)
- \(\frac{5 F}{7 M R}\)
- \(\frac{7 F}{11 M R}\)
- \(\frac{5 F}{2 M R}\)
Answer
(B) 5 F 7 M R
