Answer not displayed

   The point charges in the figure have the followingvalues: q1 = + 2.1mu C, q2 = + 6.3mu C, q3 = - 0.89mu C. Supposethat the magnitude of the net electrostatic force exerted on thepoint charge q2 in the figure is 0.58 N. Find the distance d. Express your answer using two significant figures. What is the direction of the net force exerted on q2 the figure? Express your answer using two significant figures.

Explanation / Answer

Q1=2E-6C, Q2 = 6.3E-6C, Q3=-.89E-6C Fnet = F21+F23=.58N Q2 is repelled by Q1 at 60degrees. F21 =kQ1Q2/d2<cos(60),sin(60)> Q2 is attracted by Q3 at -60degrees.F23 =kQ2Q3/d2<cos(-60),sin(60)> Replace Variables with values: F21 = <.0566/d2,.0981/d2>   and   F23= <-.0232/d2, .0437/d2> F21+F21 = <.0314/d2,.1418/d2> Solve for the magnitude and set equal to Fnet (.58 N) .1452/d2 = .58 N  solve for d: d =.5003m Replace d with value in: F21+F21 = <.1256,.5662> = tan-1(.5662/.1256) = 77.49 degrees
