A spring balance reads 196N when a metal block is suspended from it in a laboratory on Earth (g=9.8ms−2). The same block is later taken to a planet X where g=3.5ms−2.
(i) Determine the mass of the block from the Earth reading.
(ii) Calculate the reading of the same spring balance when the block hangs freely on planet X.
(iii) If an observer on planet X mistook the balance reading obtained in part (ii) to be mass expressed in kilograms, what erroneous mass value would be recorded? Show your working.
