A body is projected vertically upwards from the surface of a planet of radius `R` with a velocity equal to half the escape velocity for that planet. The maximum height attained by the body is

A

`R//3`

B

`R//2`

C

`R//4`

D

`R//5`

Text Solution

Verified by Experts

The correct Answer is:
A
`h=R/(((v_e^2)/(v^2)-1))=R/(((v_e)/(v_e//2))^2-1)=R/3`
