Two small insulating spheres with radius 5.50×10?2m are separated by a large center-to-center distance of 0.555m . One sphere is negatively charged, with net charge -1.90?C , and the other sphere is positively charged, with net charge 3.15?C . The charge is uniformly distributed within the volume of each sphere.
A) What is the magnitude E of the electric field midway between the spheres? Take the permittivity of free space to be 8.8.*10^(-12)C^2/(N*m^2)
B) What is the direction of the electric field at this point?
