A) \[\frac{3}{2}m/{{s}^{2}}\]
B) \[\frac{9}{15}m/{{s}^{2}}\]
C) \[\frac{3}{25}m/{{s}^{2}}\]
D) \[\frac{25}{7}m/{{s}^{2}}\]
Correct Answer: D
Solution :
The relation for acceleration is given by as \[a=\frac{g\,\,\sin \theta }{1+\frac{{{K}^{2}}}{{{R}^{2}}}}\] For sphere \[\frac{{{K}^{2}}}{{{R}^{2}}}=\frac{2}{5}\] So, \[\frac{{{K}^{2}}}{{{R}^{2}}}=\frac{2}{5}\] \[=\frac{25}{7}m/{{s}^{2}}\]
