Analyzing +4 | -1
Pertaining to two planets, the ratio of escape velocities from respective surfaces is 1:21: 2, the ratio of the time period of the same simple pendulum at their respective surfaces is 2:12: 1 (in same order). Then the ratio of their average densities is
View answer and explanation
Correct option: C
1:41: 4
Option C is correct. Given the ratio of escape velocities and time periods, we can derive the ratio of their average densities using the formulas for escape velocity and the time period of a simple pendulum.
