Explanation:
Detailed explanation-1: -i.e 200 N = m x 9.8, so mass of the object= 20.04 kg.
Detailed explanation-2: -How much will a body of 70 N weigh in water if it displaces 200 ml of water? (Ans. 68.04 N)
Detailed explanation-3: -But according to Archimedes principle, we know that the buoyancy force by the liquid is equal to the weight of the liquid displaced. So, the weight of water displaced = 100N.
Detailed explanation-4: -What is its mass? (g=9.8m/s2). Therefore, the mass of the body is 5.10 kg.
