Vanishing Electric Field

Electricity and Magnetism Level 1

Two charges are on the $x$ -axis. One of them is a $9\text{ C}$ charge located at $x = 0\text{ m}$ . The other is a $1\text{ C}$ charge located at $x = 1\text{ m}$ . Find the location on the $x$ -axis where the net electric field due to these charges is $0 \text{ N/C}$ .
