View answer and explanation

Correct option: A

T = 2\pi r\sqrt {\begin{array}{cccccccccccccccccccc} {\frac{{{R^3}}}{{GM}}}\\ \; \end{array}}

Option A (

T = 2\pi r\sqrt {\begin{array}{cccccccccccccccccccc}{\frac{{{R^3}}}{{GM}}}\\;\end{array}}

) is correct because dimensional analysis confirms that the dimensions on both sides of the equation match.
