Electric Field Strength
 

Electric Field Strength problem 13


In space, there are three concentric spherical shells with radii of 10 cm, 15 cm, 20 cm. The shells are evenly charged. The charges of the inner and outer shell are the same: , and the middle is charged with the charge . Calculate the electric field strength at points A, B, C, and D as shown in the figure.
