How do you find the net charge of a sphere
WebNov 8, 2024 · ΦE = ΦE(top)0 + ΦE(bottom)0 + ΦE(sides) ⇒ ΦE = EA = 2πrlE. The enclosed charge is the charge contained between the two ends of the cylinder, which is the linear charge density multiplied by the length of the segment, which is the length of the cylinder. Applying Gauss's law therefore gives: ΦE = Qencl ϵo ⇒ 2πrlE = λl ϵo ⇒ E ... http://hyperphysics.phy-astr.gsu.edu/hbase/electric/elesph.html
