A satellite is moving in a low nearly circular orbit around the earth. Its radius is roughly equal to that of the earth's radius $\displaystyle \mathrm{R}_{\mathrm{e}}$. By firing rockets attached to it, its speed is instantaneously increased in the direction of its motion so that it become $\displaystyle \sqrt{\frac{3}{2}}$ times larger. Due to this the farthest distance from the centre of the earth that the satellite reaches is R . Value of R is :
Official answer
(1)
$\displaystyle 3 \mathrm{R}_{\mathrm{e}}$
