A sphere rolls down on an inclined plane of inclination θ. What is t

Question

A sphere rolls down on an inclined plane of inclination

θ

. What is the acceleration as the sphere reaches bottom

Options:

A . 57gsinθ

B . 35gsinθ

C . 27gsinθ

D . 25gsinθ

Answer: Option A
:
A
Acceleration (a)

= \frac{g sin θ}{1 + \frac{K^{2}}{R^{2}}} = \frac{g sin θ}{1 + \frac{2}{5}} = \frac{5}{7} g sin θ .
