ANSWER:Solution 26PIntroductionHere, for the first case, we shall have to measure the mass of the steel block in air. Then, weshall have to measure the tension of the string to which the block is attached. This tensionreading will give the scale reading in the second case.Step 1:Volume of the steel block = 10 cm × 10 cm × 10 cm 3 = 1000 cm = 1000 × 10 6m 3 = 10 3 m 3 3Density of steel = 7900 kg/m(a) Mass of the steel block in air = volume × density 3 3 3 = 10 m × 7900 kg/m = 7.9 kg
