00:01
We can define our x direction of electric field as kq over x times the square root of x squared plus y squared.
00:16
Plugging in our values, we have 9 times 10 to the 9 times our q, negative 6 .5 times 10 to the negative 6, over our x and y.
00:32
We'll convert those from centimeters to meters.
00:36
We'll have 0 .1 here, 0 .1 squared plus 0 .025 squared.
00:45
This gives us an electric field in the x direction of negative 5 ,679 .61 newtons per coulomb.
00:59
Now, we would like the magnitude of the electric field.
01:06
So first, let's determine our y.
01:11
Y, our y component of electric field.
01:16
Examining our line here, our diagram, we have our line of charge.
01:23
We have it acting on this point here, which is 10 centimeters away...
