Charges of 1 nC each are placed at the vertices of an equilateral triangle with a side of 0.2 m. The resultant force acting on the fourth charge, placed in the middle of one side of the triangle, is 0.6 μN. Determine the magnitude of this charge, the intensity and potential of the field at its point of location.
