Answer:
Given:
mass of the body =70 kg
Volume of water displaced =20,000 cm
3
or 0.02 m
3
To find the weight of the body submerged in water
Mass of the solid immersed in water = mass of water displaced
= volume of water displaced × density of water
=0.02×1000=20 kg
Weight of the body, W=mg
Weight of the body in water =(70×9.8)−(20×9.8)=50 kgf
