Q2. Two point objects of equal mass M and equal charge (1 are placed on the y-axis separated by a distance Za, as shown in the figure above. Answer the following parts considering the three possibilities i) both objects have positive charge, i0) both objects have negative charge, iii) the object on top is positive and the one at the bottom is negative a} What is the magnitude and direction of the electric field at the midpoint of the line that joins both objects? b) What is the magnitude of the electric field at a point P a distance r from the masses? c) What is the magnitude of the electric field in the limit of r tends to infinity
