Chapter , Problem 71(choose chapter or problem)
In a spherical metal shell of radius R, an electron is shot from the center directly toward a tiny hole in the shell, through which it escapes. The shell is negatively charged with a surface charge density (charge per unit area) of 6.90 $ 10%13 C/m2 .What is the magnitude of the electrons acceleration when it reaches radial distances (a) r ! 0.500R and (b) 2.00R?
