(5 marks) Three point charges are located in free space as follows: Q.= -6 pic at (1,0,0), Q2= 10 uC at (2,0,0), and Q3= 4 [ac at (4,0,0). Which charge has the greatest magnitude of electrostatic force exerted on it, and what is the magnitude of that force? ’ (a a 0 Fa .69.: i .3 (Maw 2. (1 mark) Draw the electric ﬁeld lines for a negative point charge positioned at the origin. 3. (4 marks) We wish to determine the position, P(a.,b,c), in free space of a point charge Q. A positive test charge is used to explore the space around Q. When the test charge is at the Origin, the electrostatic force acting on it is in the direction - i - j. When the test charge is at (1,0,0}, the electrostatic force acting on it is in the direction — j. Find the position of the point charge. . li’%(a.lb)t) 51+ (0,0,0) 7%; ’éfce ac'ls ﬁlmy " [m 7% ai (4010)”)! 5/“ {L571} a, j e if Hp ‘Z-r (amﬂoi'zgn Mm. ...
