Here we are given the expression for electric field is equal to e vector is equal to 2 plus 5x into i cap.
00:12
I cap represents the x direction plus 3 plus 2y square units in j cap and here the unit is the unit of electric field is newton per coulum given the sides of the rectangle.
00:31
Loop that is a equal to 2 meter, b is equal to 5 meter, c is equal to 3 meter and d is equal to 4 meter.
00:45
Moving on to part a, here the x component of electric field is equal to, that is x component represents that this component which is 2 plus 5x.
00:59
At a x equal to 0 we have ex1.
01:03
Is equal to 2 newton per column.
01:08
Now at x equal to b, x equal to b means x equal to 5, then xx2 will be equal to 2 plus 5 into instead of x we are writing the value for b which is 5 meter.
01:25
So this turns out to be 27 newton per column here.
01:31
Now at y equal to d we can write here ey is equal to this is the expression for ey which is 3 plus 2y square so here 3 plus 2 into instead of d we are writing 4 meter so 4 square and this turns out to be 35 newton per column now at y equal to d plus c, we can write it here.
02:07
This is ey1, so this is ey2 will be equal to 3 plus 2 into here.
02:14
C plus d means c is 3 meter and d is 4 meter.
02:18
So altogether we have 7 meter, so 2 into 7 square.
02:23
And this turns out to be 101 newton per coulum.
02:29
Therefore, flux 51 is equal to negative of 1.
02:33
Of x1 into ac plus x2 into ac.
02:42
So this is equal to 2 into 2 into 27 minus 2...
