Two thin concentric conducting spherical shells are shown below. The smaller shell has a radius of a1 = 2 cm and carries (positive) uniform charge density of o, = + 60x10 12 C/m². The larger shell has a radius of a2 = 4 cm and carries a (negative) uniform charge density of o2 = - 40x10-12 C/m?. What is the electric field at a point 6 cm from the center of the two surfaces? Make sure you state the direction of the E field as either radially inward or radially outward.
