NEET 2026 Physics, question 34

Question 34 of the NEET 2026 paper (re-exam) is a Physics question from Electrostatic Potential and Capacitance. Its idea, Potential and Energy near a Charged Sphere, was asked 3 times, in 2024 and 2026, across NEET 2017–2026. The NTA final answer key gives option 3.

Q34 · Physics

Consider a fixed uniformly charged insulating sphere with radius R and total charge +Q. A point charge −q-q (q<<Qq<<Q) with mass m is released from rest at a distance of 3R from the centre of the charged sphere. When the point charge reaches the surface of the sphere, its speed is :

(ϵ0\epsilon_0 is the permittivity of vacuum, neglect gravitational forces).
