हिन्दीA spaceship of mass \( 2000 \text{ kg} \) is moving in interstellar space, far away from all gravitational influences, with its rockets turned off at a constant velocity of \( 500 \text{ m s}^{-1} \). What is the magnitude of the net external force acting on the spaceship?
Correct answer · Option 4
\( 0 \text{ N} \)
Explanation
According to Newton's First Law, since the spaceship moves with constant velocity (\( a = 0 \)), the net external force acting on it is \( F = ma = 0 \text{ N} \).
