The positive charge q of 15 is uniformly distributed on the circle of radius a as seen in the figure. Then +Q charge is placed in the center of the circle. Which of the following is true for this system? I. The force acting on the +Q charge is zero. I. If the load +Q is pulled from the center perpendicular to the page plane and released, it will not return to the center of the circle. The electrostatic potential energy of the +Q charge is written as 1590. IV. The magnitude of the electric field acting on +Q II. /ATEQZ is written as 159Q.
