In this case 2 charges, that is minus 50 microculum and 12 microculum are separated by a distance 8 cm.
00:13
So this is 8 cm.
00:15
We have to calculate the electric field midway between these two charges.
00:21
The electric field due to minus 15 microcule will have a direction towards minus 15 microculem.
00:32
Similarly, the direction of electric field due to plus 12 microculum will be away from the 12 microculum.
00:42
So the net electric field is towards minus 15 microculum.
00:48
Let us consider the conventional sign.
00:51
So this is positive x and therefore this is minus x direction.
00:58
So this towards left is considered as minus x direction.
01:02
So now we have to calculate the total magnetic field due to these two charges that is e will be equal to e1 plus e2 where e1 and e2 are the electric field due to minus 50 microculum and 12 microculum respectively.
01:19
So this is equal to let's write the expressions that is kq1 divided by r square plus k q2 divided by r square...
