If the radius of the earth be `6.38 x10^(4) m` and the acceleration due to gravity at earth be `9.8 ms^^(2)` then calculate the escape velocity of a body from the earth.s surface.

Text Solution

AI Generated Solution

To calculate the escape velocity of a body from the Earth's surface, we can use the formula for escape velocity: \[ v_{\text{escape}} = \sqrt{2gR} \] where: - \( g \) is the acceleration due to gravity (9.8 m/s²), ...
