Problem 3: Three point charges, Q1, Q2 and Q3, are located at the corners of two adjacent squares, with the squares sharing one edge and two corners, as shown in the figure below. The electric field produced by these three charges vanishes (E = 0) at point P, also located at one of the corners of the squares, as also shown below. Which one of the following relations between Q1, Q2 and Q3 is correct? Hints: (1) The E-field vector produced by a single point charge, Q, is given by an equation that looks something like this: E = (kQ/r²)f. Think carefully about the meaning of r and î in this equation! (2) E = 0 means: E = 0, Ey = 0, E, = 0.

= A particle with charge 9₁ = +4.7 μC is located at (x=0,y=0). A second particle with charge 92 is located at (x=0,y=4.00 cm), and a third charge 93 = +5.4 µC is located at (x=3.00 cm,y=0). (a) In your notebook, draw a diagram of the three-charge system showing the location of the charges. (b) Calculate the potential energy of this three-charge system. PE = J -8 μC

How to solve this question

Hello! I need some help on this! Consider the arrangement of two fixed point charges, equal in magnitude, shown in the figure. Which of the following statements are correct for the initial motion of a third charge if it is released from rest in the vicinity of the two charges shown?

Here are two charges of equal magnitude but opposite sign, separated by a distance s.  What is the direction (a – j) of the electric field at location 1 (marked with an X), and what is the direction (a – j) of the electric field at location 2 (marked with an X)?

Three charged metal disks are arranged as shown (cutaway view). The disks are held apart by insulating supports not shown in the diagram. Each disk has an area of 2.2 m² (this is the area of one flat surface of the disk). Use the value 8.8 12 C2/(N•m²) for €o.The charge Q1 = 4e-8 coulombs, and the charge Q2 = 2e-7 coulombs. 0.02 0.02 0.02 mm 1.7 mm ----- mm 4 mm mm F-- -+--| + A +. + В G + + + + +Qi -Q1 -Q2 +Q2 Disk 1 Disk 2 Disk 3 What is the magnitude of the electric field in the region between disks 1 and 2? = 1.07e-8 X V/m What is the direction of the electric field between disks 1 and 2? +x Which of the following statements are true?
