The acceleration due to gravity on the Earth's surface is approximately -
- A6.4 m/s²
- B10 m/s²
- C9.8 m/s²
- DMore than one of the above
- ENone of the above
Show answer and explanation
Correct answer: (c) 9.8 m/s²
Explanation
The acceleration due to gravity at the Earth's surface, g, is about 9.8 m/s². It is often rounded to 10 m/s² in simple sums, but 9.8 m/s² is the closer value.
It is a little greater at the poles than at the equator.
