** 34. A charge Q, = +3 µC is located at (-5 cm, 0) while charge Q, = -4 µC is located at (0, +5 cm). These are the two white charges in the diagram at right. 5 cm a) What is the electric field at the origin (0, 0) due to these two charges? Q,-3 μC b) If a third charge of 5 µC (the gray charge) is placed at the point (-4 cm, 3 cm), what will now be the electric field at the origin? 5 cm

Three point charges +q, +2q and +3q are located on 3 corners of a square as shown in the diagram to the right. a.What is the electric field at point P (the forth corner)?

The diagram in the attatched image shows three charges (q1, q2, q3) from left to right arranged along a straight line at the distances given. The charge at q1 is -11 μC, q2 is 7 μC, and q3 is -3 μC. a. Calculate the magnitude and direction of the net electric field E at the location of q2 b. Assuming that charges q1 and q3 are fixed (immobile), but q2 (mass = 1.5 μg) is free to move, calculate the magnitude and direction of the acceleration of q2.
