22.8 • The three small spheres shown in Fig. E22.8 carry charges 91 = 4.30 nC, q2 = -7.50 nC, and q3 = 2.60 nC. Find the net electric flux through each of the following closed surfaces shown in cross sec- tion in the figure: (a) S¡; (b) S2; (c) S3; (d) S4; (e) Sg. (f) Do your an- swers to parts (a)–(e) depend on how the charge is distributed over each small sphere? Why or why not?

Review | Const Imagine a right angle triangle with two equal sides of 10 cm. Two equal charges of +10μC are placed in the vertices corresponding to the 45° angles. A negative, -20μC charge is placed at the 90° vertex. Find the electric field in the middle of the hypotenuse. You need to provide the magnitude of the field and the direction. For the direction use the angle between the electric field and the hypotenuse (the one less than 90°). Part A - What is the magnitude of the field at the point in the midle of the hypothenuse? μA Units Request Answer Part B - What is the angle between the total field and the hypothenuse? (If the angle is not 90 degress, give the angle which is less than 90 degrees) < Return to Assignment Provide Feedback Value Submit

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!
