Question
Two infinite sheets of charge are separated by 10 cm as shown in the figure. Sheet 1 has a surface charge distribution of ?1 = 1.73 ?C/m2 and sheet 2 has a surface charge distribution of ?2 = -5.95 ?C/m2. Find the x-component of the electric field at each of the following locations:
a) at point P, 6 cm to the left of sheet 1
b) at point P', 6 cm to the right of sheet 1
Two infinite sheets of charge are separated by 10 cm as shown in the figure. Sheet 1 has a surface charge distribution of ?1 = 1.73 ?C/m2 and sheet 2 has a surface charge distribution of ?2 = -5.95 ?C/m2. Find the x-component of the electric field at each of the following locations: at point P, 6 cm to the left of sheet 1 at point P', 6 cm to the right of sheet 1Explanation / Answer
a)
E = -sigma1/2e0 + sigma2/2e0 = -1.73e-6/(2*8.85e-12) + 5.95e-6/(2*8.85e-12) = 2.38 x 10^5 N/C
b)
E = sigma1/2e0 + sigma2/2e0 = 1.73e-6/(2*8.85e-12) + 5.95e-6/(2*8.85e-12) = 4.34 x 10^5 N/C
