Explanation:
The charge on the electron is,
The electric field at a distance r from the electron is :
Where
k is the electrostatic constant,
We know that the electric field lines starts from positive charge and ends at the negative charge. Also, for a positive charge the field lines are outwards while for a negative charge the field lines are inwards.
So, the correct option is " the electric field is directed toward the electron and has a magnitude of . Hence, this is the required solution.
