Four point charges have the same magnitude of 3.6x 10-12 c and are fixed to the corners of a square that is 5.9 cm on a side. Three of the charges are positive and one is negative. Determine the magnitude of the net electric field that exists at the center of the square. Number Units the tolerance is +/-3%

Point charges of 10.4 nC and 43.9 nC are placed 0.500 m apart. What is the electric field halfway between them? Indicate direction by a positive or a negative value. Keep in mind that a positive vector is one directed to the right and a negative vector is one directed to the left. Your answer should be a positive or...
