Question

If the mass of the Sun were ten times smaller and the universal gravitational constant ten times larger, which statement is NOT correct?

G1 Physics · Accepted Answer

Step 1: Earth’s surface gravity is g=GMₑ/Rₑ², independent of Sun’s mass. Step 2: Increasing G by a factor 10 increases g on Earth tenfold, shortening pendulum period and increasing weight/fall acceleration. Thus “g will not change” is false. Final answer: D — Acceleration due to gravity on Earth would not change.
