Question Two planets have the same average density but their radii are \( \mathrm{R}_{1} \) and \( \mathrm{R}_{2} \). If acceleration due to gravity on these planets be \( g_{1} \) and \( g_{2} \) respectively, then
(A) \( \frac{g_{1}}{g_{2}}=\frac{R_{1}}{R_{2}} \)
(B) \( \frac{g_{1}}{g_{2}}=\frac{R_{2}}{R_{1}} \)
(C) \( \frac{g_{1}}{g_{2}}=\frac{R_{1}^{2}}{R_{2}^{2}} \)
(D) \( \frac{g_{1}}{g_{2}}=\frac{R_{1}^{3}}{R_{2}^{3}} \)š²PW App Link - https://bit.ly/YTAI_PWAP šPW Website - https://www.pw.live
