The acceleration due to gravity on a planet is same as that on earth and its radius is four times that of earth. What will be the value of escape velocity on that planet if it is $V_e$ on earth
Text Solution
Verified by ExpertsThe correct answer is:
B
$v = \sqrt{2gR}$ ⇒ ⇒ $\frac{v_p}{v_e} = \sqrt{\frac{g_p}{g_e} \times \frac{R_p}{R_e}} = \sqrt{1 \times 4} = 2$
∴ ∴ $v_{p} = 2 v_{e}$
