In Figure la} particles 1 and 2 have charge 41.0 \"(3 each and are held at separation distance d = 2.?0 m. {a} What is the magnitude of the electrostaticforce on particle 1 due to particle 2? In Figure lb], particle 3 of charge 41.0 11': is positioned so as to complete an equilateral triangle. (bl What is the magnitude of the net electrostatic force on particle 1 due to particles 2 and 3? [I \\\"L/ (a) (5} The figure shows three circular arcs centered at the origin of a coordinate system. On each arc, the uniformly distributed charge is given in terms of Q = 4.46 UC. The radii are given in terms of R = 10.4 cm. What are the (a) magnitude and (b) direction (relative to the positive x direction) of the net electric field at the origin due to the arcs? +90 SR -40 2R -Q R (a) Number Units v (b) Number Units
