Answer 2

Given:

The weight of body in air W = 150 N

Force of buoyancy, F = 30 N

To Find:

The weight of body in water.

Calculation:

- The weight of body in water is calculated as:

Resultant weight = Actual weight - Buoyant force

⇒ W' = W - F

⇒ W' = 150 - 30

⇒ W' = 120 N

- So, the weight of the given body in water is 120 N.
