Question

Two point charge of -16microcoulomb and +80 micro coulomb are placed 8cm apart Find the position of the point, where electric field is zero

Answer 1

Answer:

Explanation:Given that,

First charge

Second charge

Distance

Let the electric field will be zero at point O.

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.

Since,
