Question

The range of gravitational forces is: 

• A. \( 10^{-15} \) m
• B. \( 10^{-39} \) m
• C. infinity
• D. \( 10^{-2} \) m

Hint:

Gravitational force has an infinite range and is always attractive. It gets weaker with distance but never becomes exactly zero.

Answer 1

The Correct Option is C

Step 1: Understanding the Range of Gravitational Force Gravitational force is a fundamental force of nature that acts between any two masses. Unlike other fundamental forces (such as weak nuclear force or strong nuclear force), gravity: - Has an infinite range. - Gets weaker with increasing distance but never fully disappears.

Step 2: Explanation The gravitational force between two masses \( m_1 \) and \( m_2 \) is given by Newton's Law of Universal Gravitation: \[ F = G \frac{m_1 m_2}{r^2} \] where \( G \) is the gravitational constant and \( r \) is the distance between the two masses. As \( r \) increases, \( F \) decreases, but it never becomes exactly zero. This indicates that gravitational force has an infinite range.

 Thus, the correct answer is: \[ \text{infinity} \]
