Direction options include: radially outward, radially inward, the magnitude is zero

has a charge of \( -3.50 \mu \mathrm{C} \). Find the electric field at the following radii from the center of this charge configuration. (a) \( r=1.00 \mathrm{~cm} \) magnitude \( N / C \) direction (b) \( r=3.00 \mathrm{~cm} \) magnitude \( \mathrm{N} / \mathrm{C} \) direction (c) \( r=4.50 \mathrm{~cm} \) magnitude \( N / C \) direction (d) \( r=7.00 \mathrm{~cm} \) magnitude \( \mathrm{N} / \mathrm{C} \) direction
