Question

the acceleration of free fall at a planet is determined by timing the fall of. a steel ball photo electrically the ball passes B and C at times T1 and T2 after realease from A the acceleration of free fall is given by​

Answer 1

Acceleration of a free fall=g=R2GM=R2G(ρ34πR3)∝ρR

Acceleration at both earth's surface and planet's surface is same.

⟹ρeRe=ρpRp

⟹ρeρp=RpRe=dpde=1:2

________________

An object in free-fall experiences constant acceleration if air resistance is negligible. g = 9.8 m/s2.
