Question

Two point charges 80microcoulomb and 20 micro coulomb are placed 18cm apart .find the position where the electric field is zero

Answer 1

Answer:

Two point charges 20 micro coulomb and 80 micro coulomb are 10 cm apart at point A and B. The distance between O and A is (10-x) cm and the distance between O and B is x cm. Hence, The electric field will be zero at 6.67 cm distance from 80 micro coulomb..
