(Figure 1) shows four charges at the corners of a square side L.What magnitude and sign of charge Q will make the force on charge q zero? The sides of the square have a length of 0.05m. Which is the direction of the net force on the charge at the lower left? Let there be two point charges q₁ and q₂ separated by a distance d (given in the problem d = 1m). The reading will be greater than the weight of the ball sitting on it. Three charges, q1, q2 and q3 are placed left to rigth in a straight line. The normal force acting on either charge (caused by the surface of the bowl) is at a 60° angle to the horizontal. They are both positive, but the one located at x = 0 has a charge of q while the one located at x = L has a charge of 4q.
©2012-2020. They are both positive, but the one located at x = 0 has a charge of q while the one located at x = L has a charge of 4q.
