Question

1. in the formula ( g = f/m = gm/r^2 ), what does “m” represent? a) mass of the orbiting body b) mass of the central body creating the field c) momentum of the object d) radius of orbit

Explanation:

The formula \( g=\frac{GM}{r^{2}} \) is the gravitational field strength formula, where \( G \) is the gravitational constant, \( M \) is the mass of the central body (like a planet or star) that creates the gravitational field, \( r \) is the distance from the center of the central body to the point where \( g \) is measured. Option A is incorrect as the mass of the orbiting body is usually represented by \( m \) in related formulas (like \( F = \frac{GMm}{r^{2}} \)). Option C is incorrect because momentum is \( p = mv \), not related to \( M \) here. Option D is incorrect as \( r \) represents the radius (or distance), not \( M \). So \( M \) is the mass of the central body creating the field.

Answer:

B) Mass of the central body creating the field
