Answer:
Explanation:
The capacity C will decrease because it depends on the plate separation . Capacity is inversely proportional to the plate separation.
The charge will remain the unchanged because , the source of charge is battery which has been removed.
Potential difference V = Charge / capacity
As capacity decreases , V will increase , since charge remains fixed.
electric field
E = V / d ( d is plate separation )
As V increases and d also increases , E remains the same or unchanged.
