In Fig., particles 1 and 2 have charge `20.0 mu C` each and are held at separation distance d = 0.75 m. (a) What is the magnitude of the electrostatic force on particle 1 due to particle 2? In Fig., particle 3 of charge `20.0 mu 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 ?

Explanation

(a) 6.39 N, (b) 11.1 N
