Question

Approximate mass of the Earth is:

• A. \( 5.97 \times 10^{24} \) kg
• B. \( 5.97 \times 10^{24} \) tonnes
• C. \( 5.97 \times 10^{24} \) N
• D. \( 5.97 \times 10^{24} \) kN

Hint:

Mass is always expressed in kilograms in SI units. Newton is a unit of force, not mass.

Answer 1

The Correct Option is A

The mass of the Earth is approximately \( 5.97 \times 10^{24} \) kilograms. This value is used in gravitational and astronomical calculations. Units like Newtons or tonnes are inappropriate for expressing mass directly in physics.
