A spring extends by 6 cm when supporting a mass of 0.06 kg on earth. When the spring is used to support the same mass on the moon, it extends by 1 cm

      

A spring extends by 6 cm when supporting a mass of 0.06 kg on earth. When the spring is used to support the same mass on the moon, it extends by 1 cm. Determine the moon's gravitational strength. (Take gravitational field strength on earth as 10 Nkg-1)

John
Extension on earth = 6 cm caused by 0.06 kg, K = $\frac{F}{e}$ = $\frac{0.6N}{0.06}$ = 10N/m

On the moon: K = 10N/m, e = 0.01 $\rightarrow$ F = Ke = 10 x 0.01 = 0.1 N

grams on the moon = $\frac{w}{m}$ = $\frac{0.1}{0.06}$ = 1.667 N/m
