Question:

The value of g on the moon is \(\frac{1}{6}\)th that on earth. A body weighing 60kg on the earth has weight on the moon equals to?

Options:

20kg

zero

360kg

10kg

Correct Answer:

10kg

Explanation:

\(\text{Mass of the body on earth }(m_e)\text{ = 60kg}\)

\(\text{Value of g on moon, }g_m =\frac{1}{6}g_e, \text{ where }g_e, g_m \text{are gravitational acceleration on earth and moon respectively}\)

\(\text{Weight of the body on earth }W_e =mg_e = 60g_m =60×\frac{1}{6}g_e = 10g_e\)

Reading of same weighing machine on moon = \(\frac{\text{Weight of object on moon }}{g_e}=\frac{10g_e}{g_e}= 10kg\)
