The electrostatic energy stored in a capacitor with capacitance 
, with a voltage difference V applied to it, and without dielectric, is given by
Now let's assume we fill the space between the two plates of the capacitor with a dielectric with constant k. The new capacitance of the capacitor is
So, the energy stored now is
Therefore, the ratio between the energies stored in the capacitor before and after the introduction of the dielectric is

Answer:
Time taken, t = 4.86 seconds
Explanation:
Given that,
Acceleration of a particular automobile,
Initial speed of the automobile, u = 75 km/h = 20.83 m/s
Final speed of the automobile, v = 110 km/h = 30.55 m/s
We need to find the time taken to accelerate from u to v. Let t is the time taken. It can be calculate as :
t = 4.86 seconds
So, the time taken by the automobile is 4.86 seconds. Hence, this is the required solution.
