the electric potential at a distance of 2.0 m from a positive point charge is 100 v. what is the electric potential 4.0 m away from the same point charge?

Electric potential at 4m away would be 50 V.Electric potential is nothing but a collections of charges, which effects travels in the form of electric rays.we have formula for electric potential as below:V = [tex]\frac{Kq}{r}[/tex]where, V is the electric potential.q is the charge and r is the distance and K is the constant.putting th evalues for the firat case,100 = kq/2kq = 200again calculating for the 4 m distanceV = kq/r = 200/4 = 50 VHence the electric potential at the 4m away would be 50 V.To learn more about the electric potential, visit here,https://brainly.com/question/12645463#SPJ4
