With TinyTim's reminder that the whole potential difference was 50, I could solve the problem. 600 Ohms and 400 Ohms = 1000 Ohms. 600 is 3/5 of 1000. 3/5 of 50 = 30. So, the answer is 30 V.
Homework Statement
In a 50 V circuit with a 400 Ohm resistance and a 600 Ohm resistance in series; Point A is between the two resistors and point B is to the right of the 600 Ohm resistor. Charge is moving from right to left.
