Question

12..An object of weight 500N sinks in water. Weigh of water overflowed is 50 N.
a)What is the weight of the object in water?
b)If another object of the same weight floats on water, what is the weight in water?

Answer 1

Explanation:

a) Weight in water = Weight in air - weight of water overflowed = 500N−50N=450N

b) If another object of the same weight floats on water then

Weight in water = 0N buoyancy = 500N

Loss of weight in water = 500N (When a body floats on a liquid, weight of the body in air = loss of weight = buoyancy = weight of water displaced)
