Answer 1

1.100 is the correct answer

Answer 2

Hey buddy,

◆ Answer-
Weight = Zero

◆ Explanation-
When a mass m is placed in water apparent weight is given by -
W = Mg(ρ-ρ0)/ρ0

Here, balloon is filled with water
i.e. ρ = ρ0, thus-
W = Mg (ρ0-ρ0)/ρ0
W = 0

Therefore, apparent weight of water filled balloon in water is zero.

Hope it helps you...
