The figures show electric field lines arising from 2 stationary small charged particles q1 and q2. Consider the following statements.

X Incorrect. In the figure particle 1 (of charge +1.76 mC), particle 2 (of charge +1.76 mC), and particle 3 (of charge Q) form an equilateral triangle of edge length a. For what value of Q (both sign and magnitude) does the net electric field produced by the particles at the center of the triangle vanish? L. Number i 1.76 Units C/m

I need help with this question. Thank you!

Two identical thin rods of length L are each charged with a positive charge q that is uniformly distributed on each rod. The rods are arranged parallel to each other along the x direction and are separated by a distance 2d, as shown in the figure below. Determine the electric field at point P, which is located a distance d from the right endpoint of each rod. Hint: You will eventually need the following integral: น 1 S (a²+u²)3/2 du = − + C √a²+u²

You have a summer job in the Exploratorium in San Francisco. Your team has been tasked to make an exhibit where a small charged pith ball is levitated above a large charged plate with a small circular opening in the middle. The pith ball is to be suspended about 5 cm above the center of the circular opening. After sufficient testing, you know that the plate could be roughly uniformly charged with 2.5 µC/m?. You measure 9.6 cm for the diameter of the circular opening and 0.20 grams for the mass of the pith ball. Find what the charge on the pith ball should be.

A 69 g charged insulating ball hangs on a 2.052 cm long string in a uniform horizontal electric field. My Question: Find E when the charge on the ball is 145 µC.
