Question

gravity is known as a long - range force because even if two objects are very far apart, the gravity between them is______zero.
o never
o sometimes
o always

Explanation:

Gravity is a fundamental force. According to Newton's law of universal gravitation, the gravitational force \(F = G\frac{m_1m_2}{r^{2}}\), where \(G\) is the gravitational constant, \(m_1\) and \(m_2\) are the masses of the two objects, and \(r\) is the distance between them. As long as \(m_1
eq0\), \(m_2
eq0\), the gravitational force \(F
eq0\) even when \(r\) is very large. So gravity between two objects with non - zero mass is never zero.

Answer:

never
