Question

plot the graph V v/s r in case q is smaller than zero.​

Answer 1

Answer:

We have to draw a plot for the variation of electric field (E) and electric potential (V) with distance r due to a point charge Q.

We know that electric field (E) for a point charge at a distance r is E=4πε01r2Q

i.e, E   varies with r as: E∝r21

Electric potential due to a point charge Q at a distance r is V=4πε01rQ

i.e,   V∝r1
