Hi, in this question we have a question based on capacitance.
00:04
So, we have the formula for capacitance as it is epsilon ought a by d where d is the separation a is the cross section of the plate.
00:12
So, we can also write c as q by v where q starts stored in the capacitor divided by v which is also equal to epsilon ought a by d.
00:21
So, we have electric field e as v by d.
00:24
So, v is nothing but it is q into so q divided by epsilon ought into a.
00:32
So, these are the expression for capacitance and electric field.
00:37
So, here we have so for the first case we have the c decreases with increase in the value of d and for the second case so battery not connected.
00:52
So, battery is not connected therefore, charge on the capacitor remains same.
01:03
In the third case electric field is not dependent on so electric field is independent of d independent of d.
01:19
So, this is independent independent of the separation d therefore, it also remains same...
