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) what is the direction of the electric force on sphere x at the point shown in the figure? (b) Which path is sphere x likely to take when released?

Two masses of 10kg and 5kg are suspended from a rigid support as shown in figure. The system is pulled down with a force of 150N attached to the lower mass. The string attached to the support breaks and the system accelerates downwards In case the force continues to act. what will be the tension acting between the two masses ? .
