Question

SI unit of acceleration due to gravity is _____

• A. $m/s^2$
• B. $m/s$
• C. $N$
• D. $N/k{g}^2$

Answer 1

The correct option is A

$m/s^2$

The explanation for the correct option :

1. Acceleration due to gravity ($g$) is given by $g=\frac{GM}{R^2}$
2. The SI unit of acceleration due to gravity is m/s².
3. Acceleration due to gravity has both magnitude and direction, and hence is a vector quantity.

The explanation for incorrect options :

$m/s$ is the SI unit of velocity

$N$ is the SI unit of force.

$N/k{g}^2$ is not the unit of such quantity.

Hence, option A is correct.
