 First, let's find the contribution from Charge 1. The separation vector r1 points from the source to the observation (1P), so r1=2Rˆx, and ^r1=r1|r1|=2Rˆx2R=ˆx First, let's find the contribution from Charge 1. The separation vector r1 points from the source to the observation (1P), so r1=2Rˆx, and ^r1=r1|r1|=2Rˆx2R=ˆx
 Visually, this is what we know about ^r1, and what we expect for E1, since Charge 1 is negative: Visually, this is what we know about ^r1, and what we expect for E1, since Charge 1 is negative:

 Now, we can find E1 and V1. Before we show the calculation, though, we need to make an assumption about the electric potential. Now, we can find E1 and V1. Before we show the calculation, though, we need to make an assumption about the electric potential.
