Asked in NEET 2018 · g from mass, radius and density
The question asks which statement is false, so test each against how g changes.
Surface gravity on Earth is g=(GM_E)/(R²), and it involves the Earth's mass, not the Sun's.
Making G ten times larger therefore makes g ten times larger; the Sun's mass does not enter.
So g certainly does change, and the statement that it will not change is the incorrect one.
The other three all follow from a larger g: faster raindrops, harder walking, and a shorter pendulum period.
