NEET Physics Acceleration due to Gravity MCQ Question
If the acceleration due to gravity on the surface of the Earth is denoted by g, which of the following represents the formula used to calculate g in terms of the gravitational constant G, the mass of the Earth M_E, and the radius of the Earth R_E?
g = G * M_E / R_E^2
g = G * M_E * R_E^2
g = G * M_E / R_E
g = G * M_E * R_E
Correct Answer
Detailed Explanation
The acceleration due to gravity g is given by the formula g = G * M_E / R_E^2, as derived from the gravitational force equation F = G * M_E * m / R_E^2 and Newton's second law F = mg.
