How can the electric potential energy of a charged partical in an electric field be increased?
Generally, the potential energy of the system can be increased by increasing the magnitude of the particle’s charge or by reducing its distance from the source of the field (if it is positive and vice versa for a negative charge) actually, it depends on the shape and dimensions of the source. When released, P.E. of the system will decrease in case of a positive charge and vice versa if negative.
