We know that a spherical charged particle of will have an external electric field of E = k q/r2, where k = 8.988×109N·m2·C-2 is the Coulomb constant, q is the charge, and r is the distance from the center of the spherical particle. Calculate the electric field (a) for a particle with a charge of q1 = 9.15nC and at a distance of r1 = 4.84m away from the center of the particle, and (b) for a particle with a charge of q2 = 4.95nC and at a distance of r2 = 4.13m away from the center of the particle.
