Question

The escape velocity for a body of mass 1 kg from the earth surface is $11.2km{s}^{-1}$. The escape velocity for a body of mass $100kg$ would be

• A. $11.2\times {10}^{2}km{s}^{-1}$
• B. $112km{s}^{-1}$
• C. $11.2km{s}^{-1}$
• D. $11.2\times {10}^{-2}km{s}^{-1}$

Answer 1

Answer: (C)

$11.2km{s}^{-1}$

Escape velocity is independent of mass of body$.$

So$,$ body of mass $1kg$ from the earth surface is $11.2km/s.$

Hence,

option $\left(C\right)$ is correct answer.
