A particle is placed at rest inside a hollow hemisphere of radius \(R\). The coefficient of friction between the particle and the hemisphere is \(\mu=\frac{1}{\sqrt{3}}\). The maximum height upto which the particle can remain stationary is
- A \(\frac{R}{2}\)
- B \(\left(1-\frac{\sqrt{3}}{2}\right) R\)
- C \(\frac{\sqrt{3}}{2} R\)
- D \(\frac{3R}{8}\)
