Question

Two thin, isolated, concentric conducting spheres of radii 2.40 cm and 3.70 cm, have net charges of 19.00 nC and 32.00 nC, respectively. What is the electric field at 0.720 cm from the center of the spheres? Use the sign of the field to indicate direction, thus a positive electric field would point away from the center of the spheres. What is the electric potential at 0.720 cm from the center of the spheres? What is the electric field at 3.245 cm from the center of the spheres? What is the electric potential at 3.245 cm from the center of the spheres? What is the electric field at 4.540 cm from the center of the spheres? What is the electric potential at 4.54 cm from the center of the spheres?

Explanation / Answer

1)19*3/10+32*1/5 towards the sphere 2)0 3)19*3.245/2.4-32*3.245/3.7 towards from the sphere 4)19*4.54/2.4+32*4.54/3.7 away from the sphere
