A parallel plate capacitor is charged so that the potential difference between the plates is V. Then the battery and wires are disconnected. Using insulated handles, the charged plates are pulled apart to twice the original separation (d to 2d). The capacitance of the capacitor O a. increases by factor of two O b. decreases half the original value O c. stays the same O d. Can't say without numerical details
