V1=Q1/C -----> (1)
3V1=Q2/C -----> (2)

From 1 & 2

V1/3V1 = Q1/Q2.

Q2 = 3Q1.

Energy store in capacitor is directly proportional to voltage applied.

Q = CV2. Thus when voltage is tripled Q will increase 9 times.

Q~CV.
Q~C &Q~V.
So, V is 3 times and Q is also 3 times.

E=0.5cv^3.

So v triple it's 9 times.

Q=CV
C IS TRIPLED SO CHARGE IS 1/3.

becuase Q=CV
