At what xand y coordinates should a thirdparticle of charge q3=+4.0 mc beplaced such that the net electrostaticforce on particle 2 due to particles 1and 3 is zero? (A) -8.4 cm, 2.7 cm (B)
Answer» 1) First of all, we need to find the distance between the two CHARGES. Their distance on the xy plane issubstituting the coordinates of the two charges, we get2) Then, we can calculate the ELECTROSTATIC FORCE between the two charges and , which is given bywhere is the Coulomb's constant.Substituting numbers, we get and the negative sign means the force between the two charges is attractive, because the two charges have opposite Read more on Brainly.com - https://brainly.com/question/8658883#readmoreExplanation:
