Two point charges Q1 =3 nC and Q2-12 nC located along the x-axis as shown. Find the net electric potential (in Volt) at the origin O. 0.0.2m 0 como con 0.3 m

Answers

Electric potential is an scalar quantity which is given by:

V = k*Q/R

R = distance between point and charge

Now net electric potential at origin will be

Vo = V1 + V2

Vo = k*q1/r1 + k*q2/r2

here,

k = 9*10^9

q1 = Q1 = 3 nC = 3*10^-9 C

q2 = -12 nC = -12*10^-9 C

from figure: r1 = 0.3 m

r2 = 0.2 m

then, Vo = (9*10^9)*[(3*10^-9)/0.3 + (-12*10^-9)/0.2]

Vo = -450 Volt
