a) A coordinate system (with the units of metres) is set up such thatQ1=10 fC is located at the origin. Three other charges are brought in close toQ1. Theyare:Q2= -20 fC located at (2,0,0)m,Q3= 14 fC located at (0,0,2)m, andQ4= -12fC located at (-2,0,-2)m. What is the electric field~E, at the location ofQ1, due toQ2?Q3?Q4? Hence, what is the net force~FonQ1and what is the magnitude of theforce,|~F|, onQ1?
