Find the equivalent resistance. The upper left terminal connects through the 10 ohm resistor to a top horizontal wire. From that node, one branch goes downward through the 25 ohm resistor to the lower left terminal. The top wire also extends right and then downward through the 8 ohm resistor into a smaller rectangular branch on the lower right. In that lower branch, the 15 ohm resistor is on the lower left side and the 9 ohm resistor is on the right side, with both connected back to the lower wire leading to the lower left terminal.

Two point charges of +30.0 μC and -9.00 μC are 20.0 cm apart, with the negative charge to the right of the positive charge. Taking to the right as being the positive x-direction, what is the electric field midway between these two charges?
