In the figure four particles are fixed along an x axis, separated by distances d = 4.90 cm. The charges are q₁ = +3e, q2 = -e, 93 = +e, and 94 = +8e, with e = 1.60 x 10-19 C. What is the value of the net electrostatic force on (a) particle 1 and (b) particle 2 due to the other particles? d d d -X 4 (a) Number i (b) Number and Units Units 2 3
In the figure particle 1 (of charge +1.93 mC), particle 2 (of charge +1.93 mC), and particle 3 (of charge Q) form an equilateral triangle of edge length a. For what value of Q (both sign and magnitude) does the net electric field produced by the particles at the center of the triangle vanish? Number Units C-m Mi 1.93
Two particles are fixed to an x axis: particle 1 of charge q₁ = 3.09 x 108 Cat x = 21.0 cm and particle 2 of charge q2 = -5.76q1 at x = 74.0 cm. At what coordinate on the x axis is the electric field produced by the particles equal to zero? Number i Units
