[填空题]
Three positive particles oqzmut7( 1-:sfr t yppx7ckz sz/x0n;9f equal charge, x3h)bmc* 5 pn fh:vl3piz3y*s$+11.0\,\mu C\,$ are located at the corners of an equilateral triangle of side 15.0 cm (Fig. 16–50). Calculate the magnitude and direction of the net force on each particle.
the force on the lower left charge is of magnitude N, and
will point $^{\circ}$below the-x axis. The force on the lower right charge is of magnitude N, and will point $^{\circ}$below the +x axis.
