A +30 MC point charge is placed 7.0 cm from an identical +30 uC point charge. v Part A How much work would be required by an external force to move a +0.20 MC test charge from a point midway between them to a point 1.4 cm closer to either of the charges? Express your answer using two signicant gures. An electron starts from rest 41.6 cm from a xed point charge with -0.150 nC . v Part A How fast will the electron be moving when it is very far away
