Question

An object weighs 36g in air and has a volume of 8.0 cm³. What is its apparent weight when immersed in water?
Options
A 44g
B 36g
C 28g
Correct Answer
D 35g
Correct Answer

Option C is the correct answer.

Detailed Explanation

Apparent weight = weight in air - buoyant force. Buoyant force = weight of displaced water. Volume displaced = 8.0 cm³. Mass of displaced water = volume * density of water = 8.0 cm³ * 1 g/cm³ = 8.0 g. Weight of displaced water = 8.0 gf (gram-force). Apparent weight = 36g - 8g = 28g.

Hint

The buoyant force equals the weight of the fluid displaced by the object.
