Verified Solution

Answer & Solution

Correct Answer

(D) 3

Step-by-step Solution

Detailed explanation

From Kepler's law, \(T^2 \propto R^3 \Rightarrow \frac{T_1^2}{T_2^2}=\frac{R_1^3}{R_2^3}\) \(\frac{T_1}{T_2}=\left(\frac{R_1}{R_2}\right)^{3 / 2}=\left(\frac{R}{1.02 R}\right)^{3 / 2}\) \(\Rightarrow \quad \frac{T_1}{T_2}=\left(\frac{50}{51}\right)^{3 / 2}\)…
