A small 5.5 MC charge and a small 1.5 uC charge are initially very far apart. How much work does it take to bring them to a final configuration in which the 5.5 uC charge is at the point x = 2 mm, y = 2 mm, and the 1.5 uC charge is at the point x = 2 mm, y = 4 mm? Express your answer in J with one decimal place. Only the numerical value will be graded. (k = 1/4neo = 8.99 x 109 N . m 2/C 2 )
