Question

If an object has density P0, and radius R0, what happens to the object's surface gravity if the was to shrink to a size with half its initial radius, but the same density?

a. 2g0
b. g0
c. g0/2
d. g0/4

Answer 1

If an object has a density P0 and a radius R0, and it shrinks to a size with half its initial radius but the same density, the surface gravity of the object would remain the same.

Step-by-step explanation:

If an object has a density P0 and a radius R0, and it shrinks to a size with half its initial radius but the same density, the surface gravity of the object would remain the same, which is represented by option b. g0. The surface gravity of an object depends on its mass and radius, so when both the mass and radius are halved, the effect on the surface gravity cancels out, resulting in the same value.
