A simple pendulum of length $l$ and mass $m$ of the bob is suspended in a car that is travelling with a constant speed $v$ around a circular path of radius $R$. If the pendulum undergoes oscillations with small amplitude about its equilibrium position, the frequency of its oscillations will be

  • A

    $\frac{1}{{2\pi }}\,\sqrt {\frac{g}{l}} $

  • B

    $2\pi \,\sqrt {\frac{l}{g}} $

  • C

    $\frac{1}{{2\pi }}\,\sqrt {\frac{{\left( {{g^2} + \frac{{{v^4}}}{{{R^2}}}} \right)}}{l}} $

  • D

    $\frac{1}{{2\pi }}\,\sqrt {\frac{{{{\left( {{g^2} + \frac{{{v^4}}}{{{R^2}}}} \right)}^{\frac{1}{2}}}}}{l}} $

A sphere of radius $r$ is kept on a concave mirror of radius of curvature $R$. The arrangement is kept on a horizontal table (the surface of concave mirror is frictionless and sliding not rolling). If the sphere is displaced from its equilibrium position and left, then it executes $S.H.M.$ The period of oscillation will be
