A body is thrown from the surface of the earth velocity $$\mathrm{v} / \mathrm{s}$$. The maximum height above the earth's surface upto which it will reach is ($$R=$$ radius of earth, $$g=$$ acceleration due to gravity)

$$\frac{v R}{2 g R-v}$$

$$\frac{2 g A}{v^2(R-1)}$$

$$\frac{v R^2}{g R-v}$$

$$\frac{v^2 R}{2 g R-v^2}$$
