Physics - Gravitation Question with Solution | TestHub

The initial velocity$v_i$required to project a body vertically upward from the surface of the earth to reach a height of$10R$, where$R$is the radius of the earth, may be described in terms of escape velocity$v_{\mathrm{e}}$such that$v_i=\sqrt{\frac{x}{y}}\times v_{\mathrm{e}}$. The value of$x$will be
