Point A is at position (4j -3k)cm. Point B is at position -3cm k. Point C is at position (3i -2j + 5k) cm. Point D is at position 4cm j.An electric field of 4.8x10^6 N/C j is observed at the orgin. The single charge causing this field is at one of the above-named points. Which point is the charge's location, and what is the charge's value? Explain your reasoning.
