Hi, so we are to determine the y component of the electric force exerted uncharged q sub o.
00:09
So we are x, y plane.
00:17
Now let's rewrite that.
00:21
So for the force acted by k sub 1 to q ,0, they have negative or opposite charges.
00:31
So that means to attract as for force acted by a force acted by, three out two on u sub o they have opposite charges so this would repel this is the net force acted by two on uso now for the x and y components of this forces so this one this is the y and this would be the x and and we know that this is 60 degrees because we have an equidistant triangle here.
01:21
For the y component, this is net force exerted by 1 to 0 multiplied by sine theta.
01:28
This would be cosine data.
01:37
As for this second force, this is the x component, this is the y component.
01:50
This is 60 degrees.
01:51
And this is the x component.
01:59
Adding the y component.
02:08
So for this one, this is on the negative y -axis.
02:14
So that's negative f sub 1 -0.
02:18
And then sign of the angle...
