q1=+2.1?C, q2=+6.3?C, q3=?0.89?C. Suppose that the magnitude of the net electrostatic force exerted on the point charge q2 in the figure is 0.53N . Find the distance d. What is the direction of the net force exerted on

.

The point charges in the figure have the following values: q1=+2.1?C, q2=+6.3?C, q3=?0.89?C. Suppose that the magnitude of the net electrostatic force exerted on the point charge q2 in the figure is 0.53N . Find the distance d. What is the direction of the net force exerted on q2 the figure?

Explanation / Answer

Direction of force: Horizontal from left to right, since the vertical components from q1 and q3 cancel

k*q2/d^2*cos(60 deg)*(q1+q3)=F

=>d=sqrt[(9*10^9)*(6.3*10^-12)(2.1+0.89)*cos(60deg)/0.53]=0.399 m
