A number of electric charges has been placed at distinct points along a line with separations as indicated. Two charges share a common magnitude, q (lower case), and another charge has magnitude Q(upper case). The signs of the charges are indicated explicitly such that ∣∣+q∣∣∣∣+Q∣∣=∣∣−q∣∣==∣∣−Q∣∣=qQ Four different configurations of charges are shown. For each, express the net electric force on the charge with magnitude Q (upper case) as F⃗E=FE,xî where the positive x direction is towards the right. By repositioning the figures to the area on the right, rank the configurations from the most negative value to the most positive value of FE,x.

For each part make sure to include sign to represent direction, with up being positive and down being negative. A ball is thrown vertically upward with a speed of 30.5 m/s. A) How high does it rise? y= B) How long does it take to reach its highest point? t= C) How long does it take the ball return to its starting point after it reaches its highest point? t= D) What is its velocity when it returns to the level from which it started? v=

Four point charges of equal magnitude Q = 55 nC are placed on the corners of a rectangle of sides D1 = 27 cm and D2 = 11cm. The charges on the left side of the rectangle are positive while the charges on the right side of the rectangle are negative. Use a coordinate system where the positive y-direction is up and the positive x-direction is to the right. A. Which of the following represents a free-body diagram for the charge on the lower left hand corner of the rectangle? B.
