A uniformly charged, thin, semicircle has a total charge of -Q, and a radius of R. Find the electric field, magnitude and direction, at the center of the semicircle

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?

A charge 'Q' is given to thick spherical shell of inner radius 'a' and outer radius 'b'. A point charge 'q' is placed at the center. Find the charges at the surface of the conductor and electric field everywhere in space?

A negative line of charge is on the negative y axis with its top end at the origin as shown in the figure below. The charge is uniformly distributed along the line. Point P is on the positive y axiS as shown in the figure. y The the length of the line of charge is 3.17 m, the total charge on the line is -787.9 nC and point P is 3.15 m from the origin. Find the magnitude of the electric field at point P due to the line of charge.

A total charge of Q = 60 microC is split into three equal point charges located 120 deg apart on a circle defined by a radius of 4 [m] and lying in the x-y plane. Find the magnitude of the electric field at the center of the three charges. Please, provide a detailed answer with explanation and drawings to understand. Thank you in advance!

Consider a charge configuration comprising two point sources, one carrying a positive charge and the other a negative charge. The magnitude of the negative charge is three times as large as the positive charge. Construct a careful sketch of the electric field around the configuration.
