Answer:
The ratio of the new potential energy to the potential energy before the insertion of the dielectric is 0.58
Explanation:
Given that,
Length of plates = 8 cm
Width = 5.52 cm
Distance = 1.99 cm
Dielectric constant = 2.6
Length = 4.4 cm
Potential = 0.8 V
We need to calculate the initial capacitance
Using formula of capacitance
Put the value into the formula
We need to calculate the final capacitance
Using formula of capacitance
Put the value into the formula
We need to calculate the ratio of the new potential energy to the potential energy before the insertion of the dielectric
Using formula of energy
Put the value into the formula
Hence, The ratio of the new potential energy to the potential energy before the insertion of the dielectric is 0.58
