हिन्दीTwo interacting bodies forming an isolated system exert internal forces \( \mathbf{F}_{AB} \) and \( \mathbf{F}_{BA} \) on each other. The net force on the two-body system as a whole is:
Correct answer · Option 4
Zero
Explanation
Internal forces cancel in pairs (\( \mathbf{F}_{AB} + \mathbf{F}_{BA} = 0 \)), so the net force on the entire system is zero.
