two point charges are placed on the x axis as follows:
charge q1 = +4.00 nc is located at x = 0.200 m, and charge q2 = +5.00 nc is at x = -0.300 m
what ae the magnitude and direction of the net force exerted by these two charges on a negative point charges q3 = -0.600 nc placed at the origin ?

  • physic -

    draw the diagram. Notice the charge to the left attracts the q3, to the left. Now notice the q1 pulls toward the right.

    Figure the forces due to q1q3, and q2q3, which are are in opposite directions. The resultant force will be in thedirection of the larger.
