In Figure a, particles 1 and 2have charge 20.0?C each and are held at separation distance d = 1.50 m.(a) What is the magnitude of the electrostatic force on particle 1 due to particle 2? In Figure b, particle 3 of charge 20.0?C is positioned so as to complete an equilateral triangle.(b) What is the magnitude of the net electrostatic force on particle 1 due to particles 2 and 3?
