A package shows a mass of 30kg when weighed on a beam balance at the Earth’s surface.
(i) What reading in newton will be observed if the same package is hung from a spring balance at the same place? Take g=9.8m/s2.
(ii) The package is taken to the Moon where g=1.63m/s2. What will be the reading of the spring balance there?
(iii) What mass will the beam balance indicate on the Moon? Give a reason for your answer.
