The next figure shows, in cross section, a plastic, spherical shell with uniform charge Q = −16e and radius R = 10 cm.?
To find the field at point P1 at radial distance r1, we center a Gaussian sphere on the particle and with P1 on its surface.
Q: in terms of r1, what is the area ∫dA of the Gaussian sphere?
Q2: What, then, is the value of the field magnitude E at radial distance r1= 6.00 cm due to the charged particle?
E= ___ N/C
