Electric field in a parallel plate capacitor

During the charge of a capacitor, a positive charge dq is transferred from the negative plate to the positive one. But, in order to do that, it is necessary to provide a certain amount of energy in the form of work, because if it were not the case, the positive charge would be repelled by the negative plate.
