Answer 2

The total weight lost by the person is 10kg.

Given:

Weight of the person in air = 50kg

Weight of the person when displaced in water = 40kg

To find:

We need to find the overall weight loss of the person.

This can be done by considering the weight in both the mediums.

Therefore,

Using the Formula,

Total loss in weight = Weight of the person in the air - weight of the person in the water.

Substituting the values -
