Question

A body weighs 65N. Calculate its mass(g=10N/kg)

Answer 1

Answer:

m=6.5 kg

Explanation:

W= mg

65=10*m

m=6.5 kg

Answer 2

Given:

• Weight (w) = 65 N
• Acceleration due to gravity (g) = 10 m/s²

To Find:

• Actual Mass of the body?

Formula Used:

$\\ \bigstar{\underline{\boxed{\sf\pink{ Weight = Mass \times acceleration \ due \ to \ gravity }}}}$

Solution:

The Mass of the body is constant and does not change from place to place.

After substituting values,

$\colon\implies{\sf{ 65 = M \times 10 }} \\ \\ \colon\implies{\sf{ \cancel{ \dfrac{65}{10} } = M }} \\ \\ \colon\implies{\sf{ M = 6.5 \ Kg }}$

Hence,

The Mass of the body is 6.5 kilograms.

Remarks:

• Mass is a scalar Quantity.
• The mass of the body cannot be Zero.
• SI unit of Mass is Kilograms.
