HELP!! what is the resistance of a resistor if the potential difference across the resistor is 4.0 V when a current of 10 A flows through the resistor? AND Two point charges are 10 cm apart and have charges of 2uC ( the u is supposed to be a greek symbol where the left side of the u is extended down) and -2uC respectively. What is the magnitude of the electrical field at the mid point between two charges
