Question

Two point charges -Q and 2Q are separated by a distance R, neutral point will be obtained at?

Answer 1

Electric field is zero between two changes means at point electric field of both charge same . let 60-r be distance from 36 micro c charge so
k*4/r^2=k*36/(60-r)^2
1/r^2=9/(60-r)^2
take sq root both side
1/r=3/(60-r)
60-r=3r
60=4r
r=60/4=15
zero field from lager charge is 60-15=45cm
