Three small spheres x,y, and z carry charges of equal magnitudes and with signs shown in fig. They are palced at the vertices of an isosceles triangle with the distance betwwen x and y equal to the distance between x and z. sphere y and z are held in place, but sphere x is free to move on a frictionless surface.(a) waht is the direction of hte electric force on sphere x at the point shown in the figure? (b) Which path is sphere x likely to take when released?
