An object has a mass of 5kg.
a. (i) Calculate its weight in newton on the Earth. (Take g=9.8m/s2.)
b. (ii) Express this weight in kilogram-force (kgf).
c. (iii) On planet X the acceleration due to gravity is 12m/s2. Determine the weight of the same object on planet X in newton.
d. (iv) Compare the numerical values of its weight on the Earth and on planet X and state which one is larger and by what factor.
