Two point charges are on the \( y \) axis. A \( 3.00-\mu \mathrm{C} \) charge is located at \( y=1.25 \mathrm{~cm} \), and a \( -2.16-\mu \mathrm{C} \) charge is located at \( y=-1.80 \) cm. (a) Find the total electric potential at the origin. \( \mathrm{V} \) (b) Find the total electric potential at the point whose coordinates are \( (1.50 \mathrm{~cm}, 0) \).
