Question

A charged particle is held at the center of a spherical shell. The figure gives the magnitude E of the electric field versus radial distance r. The scale of the vertical axis is set by Es = 1.30×108 N/C. Approximately what is the net charge on the shell?

r (cm) (8c23p52) A charged particle is held at the center of a spherical shell. The figure gives the magnitude E of the electric field versus radial distance r. The scale of the vertical axis is set by Es 1.30x108 NC. Approximately what is the net charge on the shell? 5.29E-6 c Submit Answer Incorrect. Tries 5/10 Previous Tries

Explanation / Answer

step;1

Given that

the electric field E=1.3*10^8 N/c

distance r=0.5 cm

step;2

now we find the charge

E=9*10^9*q/r^2

1.3*10^8=9*10^9*q/(0.005)^2

charge q=7.2*10^-6 C
