Question

A rubber balloon of negligible mass is filled with $500g$ of water. Its weight in water will be

• A. $250g$
• B. $500g$
• C. zero
• D. $100g$

Answer 1

Answer: (C)

zero

Answer is C.
The weight of the water balloon in water is zero as the balloon floats on the surface of the water and does not sink into the water.
The balloon rubber floats and that the water in the balloon is the same as the water displaced. So, overall, the balloon and water would float.
