(1 point) Two point charges Q1 = 4.84 nC 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 = Q ( which is the distance from the charge Q to the field point (*)) is a positive number. Units available in Web Work (A) Find the electric potential at the origin. V = 17.7 . 10 7 J (B) If a proton is released from rest at the origin, how fast will it be moving when it is very far away from the charges? v = 168.3 m (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? v = 114.089 . 105 m
