30 POINTS Can someone please answer 3 and 4 for me

Electric field is towards the electron.

Explanation:

Given that,

The separation between an electron and a proton is,

Distance between charge to mid point,

We know that,

Charge on electron,

Charge on proton,

The net electric field due to an electron and electron at their midpoint is given by :

E = -16133.88 N/C

or

The electric field will point towards electrons or negatively charged particle. Hence, this is the required solution.
