Hi, the distance from the point where the charge q1 is located to the origin r1 is equal to root of x square plus y square, which will be equal to root of 0 .6 square plus 0 .8 square, that is equal to 1 meter.
00:22
The formula for the electric fields at a point charge q1 is e1 is equal to k into mod q1 divided by r1 square.
00:36
So we can substitute the values.
00:39
For k, it is 9 into 10 to the power 9 into 4 nanoculums, that is 4 into 10 to the power minus 9 divided by 1 meters square.
00:52
Which will be equal to 36 newton per coulum and e2 will be equal to k into mod q2 divided by r2 square which will be equal to 9 into 10 to the power 9 into 6 into 10 to the power minus 9 divided by 0 .6 .10 .5 .9 divided by 0 .6 .6 square which will be equal to 150 newton per columns.
01:33
Now e will be equal to root of e1 square plus e2 square which will be equal to root of 154 .3 newton per coulum.

Assume that theta be the angle between the line joining the charge q1 and origin from the positive x -axis, the electric field along x direction will be equal to x x as equal to e1 cos theta minus e2.
02:21
So 36 kose theta minus 150 that is equal to 36 into x by r1 minus 150 which will be equal to 36 into 0 .6 divided by 1 minus 150...
