Question

The unit of acceleration due to gravity in Newtons (N) and kilograms (kg) is:

• A. \( \text{N kg}^{-1} \)
• B. \( \text{kg N}^{-1} \)
• C. Nkg
• D. \( \text{N}^{-1} \text{kg}^{-1} \)

Hint:

\( g = \frac{F}{m} \Rightarrow \text{unit of } g = \text{N/kg} \)

Answer 1

The Correct Option is A

Newton's second law: \( F = ma \) So, acceleration \( a = \frac{F}{m} \) Since force (F) is in Newtons and mass (m) in kg, the unit of acceleration becomes: \[ \text{N kg}^{-1} \]
