Question

Two point changes +8 micro Coulomb, -16 micro coulomb are separated by 0.6m distance find the points on the line joining the charges at which potential is zero​

Answer 1

Answer:

Let the distance of the point from charge 5×10−8C be r.

Hence the distance of this point from the other charge is 16−r.

Since the potential at the point is zero,

rk(5×10−8)+16−rk(−3×10−8)=0

⟹r=10cm
