The Figure above show four charges of different signs and magnitudes q = 93 = +2Q 94 = -3Q +Q92 + q1 d = || 92 (++) 93 = -2Q III 94 All charges are separated by an equal distance d. Find the general symbolic solution for the magnitude and direction of the net force on all four charges. All answers will be a fraction reduced to its simplest form. Note if the direction is -1 (to the left) then the fraction must be negative = The solution for the first charge is shown below. You will be asked to find the other 3: F2 F3 F4 1.2 F = F2 + F13 + F14 1.2 = + k- 4 9 1.3) 4 2 1 = (11) 42 1 () k- d2 TEN TEGO TE = } = } == 2 k. k Q2 -i d2 k- Q2 d2 If Q = 245 nC and d = 20.9 cm, then what will be the magnitude and direction of F Note: units of F4 are milli-Newtons (mN). Use 3 significant figures. |F4| = mN? 2
