The value of acceleration due to gravity g on the surface of Earth depends on
A. Mass of the Earth
B. Rotation of the object
C. Mass of the object
D. Shape of the object
Answer: Option A
Solution (By JKSSB Mock Tests)
g = GM/R², where M is mass of Earth, R radius, G universal constant. It does not depend on mass of falling object (Galileo's experiment). Earth's rotation causes slight variation but surface g is primarily determined by M and R. So mass of Earth is factor.
