Question

A charge of -2.35 nC and a charge of -5.60 nC are separated by a distance of 40.0 cm. Find the position at which a third charge of +7.70 nC can be placed so that the net electrostatic force on it is zero.

_____ cm from the -2.35 nC charge

______ cm from the -5.60 nC charge

Answer 1

Here we use superposition property of electric field to solve the problem.

let bien e 2ero at distance to Hight of35 So at P E)E 2 235nc _ w2.35 nc. charge ニ 124-3|an-from-5.6nc change.
