Question

Part A A nonconducting solid sphere of radius 2.90 cm carries a uniformly distributed positive charge of 7.50x10*9 c. Calculate the magnitude of the electric field at a point 1.40 cm away from the center of the sphere Submit Answer Tries 0/15 Part B Calculate the magnitude of the electric field at a point 3.50 cm away from the center of the sphere. Submit Answer Tries 0/15 Part C Assume that the sphere is conducting. Calculate the magnitude of the electric field at a point 1.40 cm away from the center of the sphere Submit Answer Tries 0/15 Part D nitude of the electric field for the conducting sphere at a point 3.50 cm away from the center of the sphere. Submit Answer Tries 0/15

Explanation / Answer

a) E = 9 x10^9 (7.5 x 10^-9 ) [ 1.40/100 ]/ [ 2.90 / 100]^3=67.5 { 1.40 / 2.90^3} { 100^2} = 3.874 x 10^ 4 N/C

b) E = 9 x10^9 ( 7.50 x 10^-9 ) / ( 0.001225) = 5.5 x 10^ 4 N/C

c) 0

d) E =   5.5 x 10^ 4 N/C
