Four metal balls A, B, C and D having radius of 2.5 cm each are made of copper, aluminium, gold and iron respectively. The densities of copper, aluminium, gold and iron are 8.9 g/cm3, 2.7 g/cm3, 19.3 g/cm3 and 7.8 g/cm3 respectively. When the balls A, B, C and D are tied to threads, suspended from the hook of a spring balance and immersed completely in strong salty water, one by one, the apparent loss in weight will be :(1) maximum in ball B(2) maximum in ball C(3) minimum in ball B(4) same in all the balls |
