Question 2

At a distance d d\,d from an isolated point charge, the electric field strength is E E\,E and the electric potential is VVV.

What are the electric field strength and the electric potential at a distance of 4d 4d\,4d from the point charge?

Electric field strength: E4\frac{E}{4}4E​, Electric potential: V16\frac{V}{16}16V​

Electric field strength: E4\frac{E}{4}4E​, Electric potential: V4\frac{V}{4}4V​

Electric field strength: E16\frac{E}{16}16E​, Electric potential: V4\frac{V}{4}4V​

Electric field strength: E16\frac{E}{16}16E​, Electric potential: V16\frac{V}{16}16V​
