"G" is known as _:
Correct answer: B. Universal gravitational constant
- A. Gravitation of the earth
- B. Universal gravitational constant
- C. Gravitational distance
- D. None of these
Explanation
"G" in the equation for the gravitational force is known as the gravitational constant. The gravitational constant is denoted by the symbol \( G \) and is a fundamental constant of nature. Its approximate value is \( 6.67430 \times 10^{-11} \ \text{N} \cdot \text{m}^2/\text{kg}^2 \). It plays a crucial role in describing the strength of the gravitational interaction between two masses in Newton's law of universal gravitation.

About Gravitation
Newton’s law of universal gravitation relates the force between masses to their masses and separation, while gravitational field strength explains weight and orbital motion. The topic covers satellite velocity and period, escape ideas, weightlessness in free fall, and artificial gravity, which differs from ordinary gravitational attraction.
