Question
Point charges of $25.0 \textrm{ }\mu\textrm{C}$ and $45.0 \textrm{ }\mu\textrm{C}$ are placed 0.500 m apart. (a) At what point along the line between them is the electric field zero? (b) What is the electric field halfway between them?
1. $0.214 \textrm{ m}$ from the $25.0 \textrm{ }\mu\textrm{C}$ charge.
2. $2.88 \times 10^6 \textrm{ N/C}$ away from the $45.0 \textrm{ }\mu\textrm{C}$ charge.
