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

  • A

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

  • B

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

  • C

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

  • D

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