Q.No.12.2: - Suppose that you follow an electric field line due to a positive point charge. Do electric field and the potential increase or decrease?

Ans: - If we follow an electric field line due to a positive point charge then we will move away from the positive point charge because the electric field produced by a positive charge is away from charge. Electric field and electric potential both inversely dependent on the distance from the charge to the selected point (say P). So as we follow the positive charge then we will move away from the charge. The formula of electric field  and electric potential is

                    E    =    qq′/4πЄ₀r²      and       V     =     q/4πЄ₀r    

So as we follow then electric field and electric potential will decrease.
