Question

Four charges are at the corners of a rectangle. The two charges on the upper corners are of equal magnitude and opposite sign as shown in the figure. The lower two charges are in magnitude 4 times more than the upper charges and also of opposite sign. The direction of the vector that represents the electric field at a point right in the middle of the rectangle +4 points in the north direction points in the left direction is zero points in the right direction points in the south direction

Answer 1

Answer is poinin in right nighe direction Q = 4q IT to -0% lines out Electric field towards of positive charge and emerge the negative charge so, at middle point, Electric field by tq and Phe vertical components - Q and -g is towards cletric field by -q and and to is towards q there will cancel and honizentar component's will add. So net electric field at middle point in direction , fields eachother in the right
