Best answer
Correct Answer - Option 1 : 1 kg. m/s2

CONCEPT:

  • The Newton (symbol: N) is the international system of Units (SI) derived unit of force. It is named after Isaac Newton in recognition of his work on classical mechanics. specifically Newtons. the second law of motion. 
    • The units meter per second squared" can be understood as a change in velocity per time, i.e. an increase of velocity by 1 metre per second every second.
    • Where the proportionality constant m represents the mass of the object undergoing an acceleration a. As a result, the newton may be defined in terms of kilograms (kg), meters (m), and seconds (s)

EXPLANATION:

  • One newton is the force needed to accelerate one kilogram of mass at the rate of one meter per second squared in the direction of the applied force

\(1N = 1\frac{kg\:m}{s^{2}}\)

  • Hence option 1 is correct.
