Escape velocity on earth is 11.2 km/s. What would be the escape velocity on a planet whose mass is 1000 times and radius is 10 times that of earth
Text Solution
Verified by ExpertsThe correct answer is:
A
$\frac{v_p}{v_e} = \sqrt{\frac{M_p}{M_e} \frac{R_e}{R_p}} = \sqrt{\left(1000 \times \frac{1}{10}\right)} = 10$
$v_{p} = 10 \times 11.2 = 112 \mathrm{km/s}$
