Answer:
Energy stored in the capacitor will be
Explanation:
We have given edge length of capacitor =
So area A = 1.2×1.2 = 1.44
Separation is given as d 1 mm =
We know that capacitance is given by
Voltage is given as V = 12 volt
We know that energy stored is given by
To solve this problem, we will apply the concepts related to Faraday's law that describes the behavior of the emf induced in the loop. Remember that this can be expressed as the product between the number of loops and the variation of the magnetic flux per unit of time. At the same time the magnetic flux through a loop of cross sectional area is,
Here,
= Angle between areal vector and magnetic field direction.
According to Faraday's law, induced emf in the loop is,
At time , Induced emf is,
Therefore the magnitude of the induced emf is 10.9V
