Sketch the electric field lines for the system of charges described in Problem 35.
IP The point charges in Figure 19−33 have the following values: q1 = +2.1 μC, q2 = +6.3 μC, q3 = −89 μC. (a) Given that the distance d in Figure 19−33 is 4.35 cm, find the direction and magnitude of the net electrostatic force exerted on the point charge q1. (b) How would your answers to part (a) change if the distance d were doubled? Explain.

Step 1 of 2
Here we need to draw the electric field lines for the given system of charges.
An electric field line is an imaginary line or curve drawn through a region of space so that its tangent at any point is in the direction of the electric-field vector at that point. .
In all the cases, if we place a unit positive charge in the given configuration. The path followed by the charge will be same as that of the electric field lines, in all the cases. Because the field lines are the path followed by the unit positive charge, when placed in the given configuration.
