"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.
