Hi, here in this given problem to compare the charge given stored over the capacitors we use an expression for the charge stored over the capacitor and that is given as q is equal to c multiplied by v, c is the capacitance.
00:30
Here an expression for the capacitance of a parallel plate capacitor that is c is equal to epsilon naught a by d.
00:39
So, charge may be given as epsilon naught a v by d, a is the area of the plates of the capacitor, d is the gap between them, v is the potential.
00:51
So, in the first part of the problem, here we will not convert the given areas or gap between the plates in m k l, we will convert the cgs or cgi units, cgs units, we will remain them as it is.
01:08
So, in the first case the charge q 1 that will be given by epsilon naught, area of the plate that is given as 10 centimeter square.
01:18
So, we keep it as 10 centimeter square only, we are not converting it into meter square, multiplied by 10 volt, gap between the plates this is given as 2 millimeter and i am using it as millimeter only, as we need not to find the exact value of the charge, we have to just compare it.
01:39
So, it comes out to be equal to 50 epsilon naught units.
01:46
Then in the second part, epsilon naught area of the plates that is given to be 5, potential difference applied 10 volt, gap between the plates 1 millimeter only.
01:58
So, it also comes out to be equal to 50 epsilon naught units...
