Question

Charge of uniform density (40 pC/m2) is distributed on a spherical surface (radius = 1cm), and a second concentric spherical surface (radius = 3 cm) carries a uniform charge density of 60 pC/m2. What is the magnitude of the electric field at a point 4cm from the center of the two surfaces? 3.8 N/C 0 3.2 4.1 N/C

Step 1

Given: - Inner surface charge density, sigma_i = 40 pC/m^2 - Outer surface charge density, sigma_o = 60 pC/m^2 - Inner surface radius, r_i = 1 cm = 0.01 m - Outer surface radius, r_o = 3 cm = 0.03 m Total charge, Q = 4πσ_i r_i^2 + 4πσ_o r_o^2 Q = 4π(40 × Show more…
