Answer:
Explanation:
Given
Diameter of Plates is D
distance between Plates is d
Energy Stored in the Plates is U
Suppose fixed Potential is V
Energy is given by

where C=capacitance

where A=area of Plates

Thus 
Keeping all other factors as same

For triple the Energy

divide 1 and 2 we get


Thus the diameter should be change to
times of original value
