Question

The value of g on moon in 1/6 th of the value of g on earth. A man can jump 1.5 m high on the earth. He can jump on the moon up to a height of:

• A. 9 m
• B. 7.5 m
• C. 6 m
• D. 4.5 m

Answer 1

Answer: (A)

9 m

Answer is A.
Because the moon has less mass than Earth, the force due to gravity at the lunar surface is only about 1/6 of that on Earth.
If a man can jump $1.5$ m high on the earth, he jump to a height of $1.5\times 6=9$ m.
Hence, he can jump on the moon up to a height of 9 m in the moon.
