A) \[6\,m\]
B) \[\frac{2}{3}\,m\]
C) \[\frac{2}{9}\,m\]
D) \[18\,\,m\]
Correct Answer: D
Solution :
It is given that, acceleration due to gravity on planet A is 9 times the acceleration due to gravity on planet B i.e., |
(i) |
From third equation of motion |
At planet A, (ii) |
At planet B, (iii) |
Dividing Eq. (ii) by Eq. (iii), we have |
From Eq. (i), |
or |
