Question

Nkg-1 is the unit of which physical quantity
​

Answer 1

Answer:

The unit of force is the newton (N), and mass has the SI unit kilogram (kg). One newton equals one kilogram metre per second squared. Therefore, the unit metre per second squared is equivalent to newton per kilogram, N·kg−1, or N/kg.

Answer 2

Answer:

NKg⁻¹ is the unit of acceleration.

Explanation:

Given that :

• S.I. unit of unknown physical quantity is NKg⁻¹.

Solution :

• Since, N (Newton) is S.I. unit of force.
• When a force, F is applied on a body of mass m, it produces an acceleration of a.
• Mathematically, F = ma
• S.I. unit of mass is Kg
• S.I. unit of acceleration is m/sec².
• So, S.I. unit of force is N = Kg m/sec² .
• Putting value of N into S.I. unit of unknown physical quantity, we get;
• S.I. unit of unknown physical quantity = Kg m/sec² x Kg⁻¹

⇒ S.I. unit of unknown physical quantity = m/sec².

• Since, m/sec² is S.I. unit of acceleration.
• The unknown physical quantity is acceleration.
