Electric Field and Potential of Center of Square

  1. Dec 2, 2006 #1
    Four Charges q1 = 1nC, q2 = -1nC, q3 = 3nC, and q4 = -3nC are placed at the corners of a square located in the plane xy, with size of length L 1m, as follows: q1 at (0,0); q2 at (1,0); q3 at ( 1,1); and q4 at (0,1). Calcuate the electric field at point P located in the middle of the square and find the electric potential at the same point!


    Could someone please help me solve this! thanks

    Show some work please. What are the equations for the electric field and electric potential from a single charge? Are these quantities vectors or scalars?

    how to solve this "charges of +6,+12and+24uc are placed at threecorner of square. what charge should be placed at the remainig corner in order to have zero potential at the centre of the sqare ??
