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.

Field points where V falls fastest: Eₓ = -∂V/∂x for each component. If V is the same everywhere in a region, E = 0 .
AIPMT 2010NEET 2015NEET 2020
Spheres joined by a wire reach equal potential, not equal charge : charge divides as R, and surface density goes as σ∝1/R .
AIPMT 2012NEET 2019NEET 2021
With the battery removed, Q stays fixed. A dielectric makes C → KC and V, E fall by K ; pulling the plates apart raises V.
AIPMT 2006AIPMT 2010NEET 2015
Joining a charged capacitor to an identical uncharged one keeps the charge but halves the total energy ; the lost half is dissipated as heat .
NEET 2017NEET 2022
A capacitor's energy lives in the field between its plates: u = (1/2)ε₀E² per unit volume, so U = (1/2)ε₀E² × Ad.
AIPMT 2001AIPMT 2012NEET 2021
Inside a charged conducting sphere or shell, E = 0 but the potential is constant and equal to the surface value kQ/R, not zero.
