- 1) What must be the distance between point charge Q1 = 26.0 µC and point charge
- Q2 = -47.0 µC for the electrostatic force between them to have a magnitude of
- 5.70 N?
- [ d= 1.39 m]

- (27) In Figure, two curved plastic rods, one of charge +q and the other of charge - q, form a circle of radius R = 8.50 cm in an xy-plane. The x axis passes through both of the connecting points, and the charge is distributed uniformly on both rods. If q =15.0 pC, what are the (a) magnitude and (b) direction (relative to the positive direction of the x axis) of the electric field E produced at P, the center of the circle?
