हिन्दीIn SI units, force is defined using the formula \( F = k m a \). The value of the proportionality constant \( k \) is set to 1 because:
Correct answer · Option 2
unit force (1 N) is defined as the force that produces an acceleration of \( 1 \text{ m s}^{-2} \) on a mass of \( 1 \text{ kg} \)
Explanation
In SI units, 1 Newton is defined specifically as the force that produces an acceleration of \( 1 \text{ m s}^{-2} \) on a mass of \( 1 \text{ kg} \), making \( k = 1 \).
