Non-Uniform Charged Ring: −∫E·dl (∞ se 0) kitna? | Potential at Centre | NEET

Ring (radius 0.5 m) pe 1.11 × 10⁻¹⁰ C charge NON-uniformly faila hai. −∫E·dl, infinity se centre tak, kitna hoga? Answer: lagbhag 2 V. Trap: non-uniform dekh ke lagta hai field nikaalna padega. Par −∫E·dl to bas centre ka potential hai, aur saara charge R doori pe hai, chahe kaise bhi faila ho. V = kq/R ≈ 2 V. Ratto mat. Samjho. #NEET #Electrostatics #ElectricPotential #NEETPhysics #JEE
