Question

State with reasons whether the sentence is  true or false .

The escape velocity on the moon is less than that on the earth.

Solution

Escape velocity on a planet is given as:

\[v_{ \text{esc} } = \sqrt{\frac{2GM}{R}} = \sqrt{2gR}\]
Since, acceleration due to gravity on Moon is one-sixth of that on Earth, thus the escape velocity on the Moon is less than that on the Earth. Hence, the statement is true.
