Take weights of five of your friends. Find out what their weights will be on the moon and the Mars.

Answer»

The weight of a body

(i) On the earth. W1 = mg1

(ii) on the moon, W2 = mg2

(iii) on Mars, W3 = mg3

∴ W2 = W1 × \(\frac{g_2}{g_1}\) and W3 = W1 × \(\frac{g_3}{g_1}\)

Now, g1 = 9.81 m/s2, g2 = 1.67 m/s2 and g3 = 3.72 m/s2

If W1 = 500 N,

W2 = 500 × \(\frac{1.67}{9.81}\) N = 85.12N(approx.)

and W3 = 500 × \(\frac{3.72}{9.81}\) N = 189.6 N (approx.)
