If a charge is is located inside a shell of uniform charge, there is no net electrostatic force on the particlefrom the shell.explanation?

Same thing as the gravitational analog. (both are inverse-square forces).

Simply put, the farther to the 'right', say you move inside such a shell, the closer you are to the right 'wall'. however, more of the total charge is now to the left of you, if more distant.

if you perform the volumetric integration, you see that these opposing modifications cancel:

(scroll down to 'inside the shell', change some constants, good2go.)


hope that helps,
