Question

A 70 g substance has a volume of $35c{m}^3$. It will float on the surface of the water.

• A. True
• B. False

Answer 1

The correct option is B False

Given:
Mass of substance $=70g$.
Volume of substance $=35c{m}^3$
density of water $=1g{m}^{-3}$
By using the formula,
Density $=\frac{Mass}{Volume}$
Density of sub stance $=\frac{70}{35}=2g{m}^{-3}$
since, the density of the substance is more than the density, the gravitational force acting on it will be stronger than the buoyant force of water acting it, it will sink and not float on the surface of water
