Answer:
First find electric field at mid point because of Q1(0.2 micro coulomb), by using formula. E1 = KQ1/r^2, here r = 0.05 m
Explanation:
two point charges 1.0 micro C and -0.25 micro coloumb are placed in air at a distance 0.40m from each other.find out at wich point on the line joining the two charges should a third charge be placed so that no force acts upon it?
