Hello everyone, we are going to understand this question.
00:06
Here, given in the question, the electric field strength in the space between two closely spaced parallel disk, that is, e is equal to 1 .0 into 10 to the power 5, newton per coulomb.
00:29
This field is the result of transferring 2 .9 into 10 .9 electrons.
00:35
So number of electrons are getting transfer and is equal to 2 .9 into 10 to the power 9 electron.
00:46
From one disk to other disk.
00:48
What is the diameter of disk? so we have to find the diameter of disk.
01:00
Now, value of e is given diameter of disk that we have to find.
01:08
Charge on electron, e is equal to 1 .6 into 10 to the power minus 19 cologne, value of epsilon knot that is 8 .85 into 10 to the power minus 12 coul fulom square per newton meter square.
01:28
So we know that capacitance of parallel plate capacitor that is represented by c which is epsilon not a upon d and electric field e is equal to potential difference upon distance between the plate and and q is equal to c into v.

Total chart that is n into e is equal to here substituting the value of c...
