A spherical charge distribution of radius R is given by  ρ = ρ0(1 – r/R), where r is the radial distance and ρ is the volume charge density.  The electric field E is maximum at r equals:   Zero  2.0R R/3 2R/3 0.745R Clear my choice

There are three static charges (Q1 = 4 nC, Q2 = - 4 nCn and Q3 = - 4nC) located in different locations of Fig. 1. Calculate the net electric field at the given point P.

ric Fields due to Point Charges An uneven dipole is located along the x-axis and centered on the origin as drawn. Its positive end has twice as much 2a 1 charge as its negative end. Each charge is located a distance a away from the origin along the x-axis. In terms of k, q, and a, find the electric field vector only at а POINT 1 and POINT 2. Your answers should be simplified 2 numerically until they are in the form: E = (0.123, -2.345), for example. -2a +29 2a
