An iron sphere weighs 5.88N on the surface of the Earth where g=9.8ms−2. The same sphere is taken to the surface of the Moon where g=1.63ms−2. The radius of the sphere is 1.5cm. Take π=3.14.
(i) Calculate the mass of the sphere.
(ii) Determine its weight on the Moon.
(iii) Compute the volume of the sphere.
(iv) Using your results, find the density of iron based on the Earth data.
(v) Will the numerical value of the density change if it is calculated on the Moon? Give a brief justification.
