All right, so in this problem, we have a point. Charge? Whose charges? Q equal one like we're cool. So we want to find out the location off one point whose potential is 100 volts. So the potential expression of the point charges you equal one over four pi. Absolute lots times Que of our where are is that this is the distance from this From this form. The point charge to this location and the queue is right here. So this equal 100 volts an agency that are this case equal 90 meters and suppose willing to find out the location where the point that we're the potential is 200 volts. If the potential is 200 volts and you can just utilized the same technique and to find that are in this case Mayko 45 meters. Okay?
