A positive charge of $q_1$ is located $3 \mathrm{m}$ to the left of a negative charge $-q_2$. Magnitude of charge $q_1$ greater than magnitude of negative charge $q_2$. The net electric field intensity is zero at a point on the line passing through charges and $1 \mathrm{m}$ to the right of $-q_2$. On this line there are also points where the potential is zero. Location of these two points relative to the negative charge is/are
