5. A solid metallic sphere has a radius of 4 m as shown in the figure. The sphere has two empty spherical cavities, each of radius 0.5 m. Inside the two cavities, there are free charges located at ry = 2ſ + 2Ń (91 = 2q), and , = 2ſ – 2Â (92 = 9). Calculate the electric field at the field point r= 7jm. Show all mathematical steps and explain your solution in detail (1 point). z . 9,= 29 1r : 79 --959 X
