A cylinder of mass \(M_c\) and sphere of mass \(M_s\) are placed at points \(A\) and \(B\) of two inclines, respectively (See Figure). If they roll on the incline without sipping such that their accelerations are the same, then the ratio \(\frac{{\sin \,{\theta _c}}}{{\sin \,{\theta _s}}}\) is

- A \(\sqrt {\frac{8}{7}} \)
- B \(\sqrt {\frac{15}{14}} \)
- C \(\frac{8}{7}\)
- D \(\frac{15}{14}\)
Answer & Solution
Correct Answer
(D) \(\frac{15}{14}\)
Step-by-step Solution
Detailed explanation
