$25\%$ Part $($a$)$ As a function of the radial distance from the center of the spherical shell, what is the magnitude of the electric field for $25\%25\%r>R25\%r>R0?$

$25\%$ Part $(b)$ What $is$ the direction $of$ the electric field for $0?$

radially outward

$$ Correct!

$25\%$ Part $(c)As$ a function $of$ the radial distance from the center $of$ the spherical shell, what $is$ the magnitude $of$ the electric field for $r>R?$

$25\%$ Part $(d)$ What $is$ the direction $of$ the electric field for $r>R?$

can you explain part b as well, thank you
