Question

In which regions, electric field can be zero for given arrangement of an electron and two protons?

[e : electron, P : proton]

Answer 1

Thus the electric field between electron and proton will be zero in case I and III.

Explanation:

• In case IV the electron is situated faraway from that point.
• So force due to electron can not be balanced by the force on proton.
• But in case I ans III the forces between these charges can be changed and the electric filed between them will become zero.
• Thus the electric field between electron and proton will be zero in case I and III.
