A rocket of mass \[M\] is launched vertically from the surface of the earth with an initial speed \[V\] Assuming the radius of the earth to be \[R\] and negligible air resistance, the maximum height attained by the rocket above the surface of the earth is

\[R\left( \frac{2gR}{{{V}^{2}}}-1 \right)\]

\[R/\left( \frac{gR}{2{{V}^{2}}}-1 \right)\]

\[{{R}_{{}}}\left( \frac{gR}{2{{V}^{2}}}-1 \right)\]

\[R/\left( \frac{gR}{2{{V}^{2}}}-1 \right)\]
