Answer:
The electric field points to the left because the force on a negative charge is opposite to the direction of the field.
Step-by-step explanation:
In an electric field, a positive charge has tendency to move from high to low potential and hence experience the electric force in the direction of electric field since electric field lines are directed from high to low potential.
In an electric field, a negative charge has tendency to move from low to high potential and hence experience the electric force in the direction opposite to electric field since electric field lines are directed from high to low potential.This phenomenon happened because The electric field from a positive charge will points away from the charge while the electric field from a negative charge will points toward the charge.
