2. Now you try one. Suppose that charge 1 has a magnitude of +6.00μC, charge 2 of +5.00μC, and charge 1 is located at 4.00cm i +3.00cm ĵ and charge 2 is located at 6.00cm î-8.00cm j. Find F12 and find F2, in component form. Show all calculations below. (Check with another group before you move on.) 3. In the following exercise you are given three "charges"; actually solid circles on a flat board which you are to imagine are point-like electric charges. A coordinate system has been established at one corner of the board, with the x and y directions specified. Using a ruler you can determine the position vectors r₁, 2, and r3 which specify the displacements of the "charges" from the coordinate origin. Carefully measure these displacements, recording your answer below. Be careful about units. r₁ 12 13 = ( =( = ( )i + ( )Î + ( )i + ( r12 = ( r31 = ( r23 = ( 4. Using these displacements, find the relative displacements r=r₁-r; and the charge-to- charge distances raj. + )i + ( )i )i + ( As a check on your calculation, what relationship must hold between the vectors r12, r31, and r23?
