4. What is the magnitude of the force on the +4Q now?(a) 16F (b) 4F (c) F (d) F/4 (e) other28. Two identical loops of the wire carry identical current i. The loops arelocated as shown in Figure 20. Which arrow best represent the directionof the magnetic field at the point P midway between the loops?Next we move the +Q and +4Q charges to be 3 times as far apart as theywere before as shown in Figure 3.:i(a) (b)(c)+QFigure 3+4QP(d) (e) Zero5. What is the magnitude of the force on the +4Q now?i(a) F/9 (b) F/3 (c) 4F/9 (d) 4F/3 (e) other6. Which of the arrows is in the direction of the net force on charge Bshown in Figure 4?Figure 20-1 +1A B+1CFigure 4(a) (b) (c)(d) (e) None of theseThe four separate figures in Figure 21 involve a cylindrical magnet and atiny light bulb connected to the ends of a loop of cooper wire. These figuresare to be used to answer Question 29. The plane of the wire loop isperpendicular to the reference axis. The states of motion of the magnetand of the loop of wire are indicated in the diagram. (Speed will be representedby v and CCW represents counter clockwise7. Figure 5 shows a particle (labeled B) which has a net electric charge of+1 unit. Several centimeters to the left is another particle (labeled A)which has a net charge of -2 units. Choose the pair of force vectors(the arrows) that correctly compare the electric force on A (caused byB) with the electric force on B (caused by A).-2 units +1 unitAFigure 5B(a)(b)(c)Force on A Force on B Force on A Force on B(d)(e)Figure 214Prepared by Dr. J.J.Applied Sciences Education ResearchGroup, FSG, UiTM, Shah AlamCall: 03-55444593; H/P:019-355-1621Email: drjjlanita@hotmail.comWeb:http://drjj.uitm.edu.my13Prepared by Dr. J.J.Applied Sciences Education ResearchGroup, UiTM, Shah AlamCall: 03-55444593; H/P:019-355-1621Email: drjjlanita@hotmail.comWeb:http://drjj.uitm.edu.my
