## Homework Statement

please some one help me with this problem:

Consider a thin spherical shell of radius 18.7cm with a total charge of 2.60μC distributed uniformly on its surface. Find the electric field, in N/C, at a radius of 32.4cm from the center of the charge distribution.

i used this equation:

E=Q/(4 x Pi x Eo x r^2)

this question was a quiz and i think i got it wrong. please help

## Homework Equations

E=Q/(4 x Pi x Eo x r^2)

in this case : Q is 2.6e-6

and r= 32.4

Eo=8.854e-12

## The Attempt at a Solution

E=2.6e-6/( 4 x pix 8.85e-12 x 32.4^2)

= 22.26N/C

i plugged in all the number and i got 22.26 whick is wrong. dont know wat i did wrong here
