Question

If the radius of the earth were to shrink and its mass were to remain the same, the acceleration due to gravity on the surface of the earth will?

• A. Increase
• B. Decrease
• C. Zero
• D. Remain the same

Answer 1

The correct option is A

Increase

As, acceleration due to gravity, $g={\frac{G\ast M}{R}}^2$
Where G is the constant and M is also not changing. So if R decreases, g increases
