NCERT lines NEET asked again and again

Read these lines from your NCERT book twice: NEET has built questions on each of them more than once.

vₑ = √(2GM/R) does not depend on the mass or direction of the projectile, and vₑ = √2 vₒ for a near-Earth orbit .

T² ∝r³ gives period ratios for planets and satellites, and equal areas in equal times means vₘₐₓ/vₘᵢₙ = rₘₐₓ/rₘᵢₙ .

Going down, g falls linearly with depth : g' = g(1 − d/R), so it is half at R/2 depth. Going up, it falls as 1/(R + h)² .

NEET 2017NEET 2019NEET 2020

Since g = GM/R², a planet's g scales as M/R² , and the Earth's mean density comes out as ρ = 3g/4πGR .

AIPMT 2005NEET 2023NEET 2024

Lifting a mass from the surface to h = R costs 1/2 mgR , not mgR, because g weakens on the way: ΔU = mgh/(1 + h/R).

G is a universal constant, so the pull between two masses is the same in air, liquid or vacuum . Two free-floating astronauts drift towards each other .
