  02.39: A parallel-plate capacitor is connected to a resis*u uu 9wbxbuk07n.y0e tanceless circuit with a battery having emf E until the c0uwebu.*9k 7nbxu 0 yuapacitor is fully charged. The battery is then disconnected from the circuit and the plates of the capacitor are moved to half of their original separation using insulated gloves. Let Vnew be the potential difference across the capacitor plates when the plates are moved together, Vold be the potential difference across the capacitor plates when connected to the battery. Vnew/Vold=?
