How much work is required to move a negative charge, of q = -80 µC and m 50 g, from point '1' to point 2 along the x-axis away from the long uniformly charged line that is parallel to the y-axis as shown in the figure below? The initial and final positions of the charge are a = 10 cm and b = 15 cm and the linear charge density of the line is K = 10 nC/cm. K a The work required, W = Units Select an answer V If the same charge is released from rest from point '2', what will be the speed of this charge as it passes point '1? The speed at '1', v = Units Select an answer
