Question asks: A point charge q = 4.9 μC is placed at each corner of an equilateral triangle with sides 0.25 m in length. What is the magnitude of the electric field at the midpoint of any of the three sides of the triangle?If you can solve for any midpoint in the triangle and you are given the distance between each point, why do you have to solve for the height of the triangle in order for the problem to be right?

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

Problem 6: A positive charge of magnitude Q; = 0.45 nC is located at the origin. A negative charge Q2 = -3.5 nC is located on the positive x-axis at x = 12 cm from the origin. The point Pis located y = 18 cm above charge Q2. y R Q2 X ©theexpertta.com Part (a) Calculate the x-component of the electric field at point P due to charge Qj. Write your answer in units of N/C. Ex 1 =

The drawing shows a positive point charge q1, a second point charge q2 that may be positive or negative, and a spot labeled P, all on the same straight line. The distance d between the two charges is the same as the distance between q1 and the spot P. With q2 present, the magnitude of the net electric field at P is twice what it is when q1 is present alone. Given that q1 = 0.50 μ C, determine q2.

A cube has positive charge +Q in all corners except for one, which has a negative point charge - Q. Let the distance from any corner to the center of the cube be r. What is the magnitude and direction of the of electric field at the center of the cube (point P)?

Points A, B, and C are at the vertices of an equilateral triangle. A certain positive charge q placed at A produces an electric field of magnitude 623 N/C at C. Suppose a second, identical charge is placed at B. What is the magnitude of the new electric field at C?

In the figure, the point charges are located at the corners of an equilateral triangle 29 cm on a side. A. Find the magnitude of the electric field in N/C at the location of qa, given that qb = 10.8 μC and qc = –5.9 μC .  B. Find the direction of the electric field at qa in degrees above the negative x-axis with origin at qa.  C. What is the magnitude of the force in N on qa, given that qa = 1.7 nC?  D. What is the direction of the force on qa in degrees above the negative x-axis with origin at qa?
