Step-by-step explanation:
An electron has a negative charge and a proton is a positively charged particle. Electric field lines are used to express the direction of the electric field. For a positive charge, it is outwards while for a negative charge it is inwards. The attached figure shows the electric field lines between a proton and an electron. The field lines emerge from proton and terminate at electron.
The electrical force between charges is given by :
![F=k(q_1q_2)/(r^2)](https://img.qammunity.org/2021/formulas/physics/college/mp5zw5wxesiddn2lg0t4s9x2io5sxysz5a.png)
r is the distance between charges
The force is directly proportional to the product of charges. It means that if the product of electrical charge increased, it means that the electrical force will increase proportionally.
