266436 A satellite is moving around the earth. In order to make it move to infinity, its velocity must be increased by-

1

20 %

2 it is impossible to do so

For escaping: U + K.E. $= 0$
$\begin{aligned} \Rightarrow V_{e} = \sqrt{\frac{2 G M}{r}} & V_{s} = \sqrt{\frac{G M}{r}} \\ ∴ Δ V = \frac{V_{e} - V_{s}}{V_{s}} \times 100 % \\ = (\sqrt{2} - 1) \times 100 % \\ = Δ V = 41.4 % \end{aligned}$
