Answer to Question #189184 in Field Theory for Tooba Tahir

Question #189184

Electric field and electric potential at a point 3cm away from a point charge is E and V respectively. What is the electric field and electric potential at 9 cm away from the same charge.

Expert's answer

"E'=\\frac{3^2}{9^2}E=\\frac{1}{9}E"

"V'=\\frac{3}{9}V=\\frac{1}{3}V"
