The acceleration due to gravity on the planet A is 9 times the acceleration due to gravity on planet B. A man jumps to a height of 2 m on the surface of A. What is the height of jump by the same person on the planet B ?

A

`(2//9)`m

B

18 m

C

6 m

D

`(2//3)`m

Text Solution

Verified by Experts

The correct Answer is:
B
The velocity of the mass while reaching the surface of both the planets will be same.
i.e., `sqrt(2g.h.)=sqrt(2gh)`
`sqrt(2xxgxxh.)=sqrt(2xx9gxx2)`
`:. 2h.=36 rArr h.=18`m.
