A rocket is launched vertical from the surface of the earth of radius

R

with an initial speed

v

. If atmospheric resistance is neglected, then maximum height attained by the rocket is

View answer and explanation

Correct option: A

h=\frac{R}{\left(\frac{2 g R}{v^2}-1\right)}

Option A (

h=\frac{R}{(\frac{2 g R}{v^2}-1)}

) is correct because it correctly applies the conservation of energy principle to find the maximum height.
