Question

Two conducting hollow spheres are co-centered. The inner sphere has a charge q=+0.8x10^-6 C and a radius of 10 cm. The outer sphere has a charge Q= -3.0 x10^-6 C and a radius of 30 cm. What is the electric field (in N/C) at a point P, 20 cm from the center of the spheres? a. 1.8x10^5 b. 1.6x10^5 c. 3.2x10^5 d. 3.6x10^5 e. 0.8x10^5

Step 1

This means that the electric field due to the outer sphere at point P (which is inside the outer sphere) is zero. Second, we need to calculate the electric field due to the inner sphere at point P. The formula for the electric field due to a point charge is E = Show more…
