am finished O (1 point) + Two point charges Q1 = 4.84nC and Q2 - -3.44nC are shown in the figure. Q1 is located at (-1.8 cm, 0.0 cm) while Q2 is at (0.0 cm, 2.3 cm)). Hint: The r in the equation V = 42 ( which is the distance from the charge Q to the field point (*)) is a positive number.

V = (C) If an electron has a speed of 1.11 x 107 very far away from the charges shown above, how fast would it be moving at the origin? U =
