उत्तर

The statement is true.

Reason:

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.
