Answered by Nick
Particles 1 and 2 have charge 20uC each and are held at separation distance d=1.50m. (a)What is the magnitude of the electrostatic force on particle 1 due to particle 2? Particle 3 of charge 20uC is positioned so as to complete an equilateral triangle. (b) What is the magnitude of the net electrostatic force on particle 1 due to particle 2 and 3?
