Three point charges are located at the corners of an equilateral triangle, whose side l = 0.5 m. The charges have magnitude -7.00 μC, 2.00 μC and 2.00 μC respectively. (a) Calculate the total electric potential energy of these charges. (b) How much work must be done to move the 2.00 μC charge to infinity, leaving the other two charges in place? (d) Find the (net) electric field at the midpoint between the 2.00 μC and -2.00 μC charges.
Three charges are positioned at three corners of a square of side length a = 0.5 m as shown in the figure. The charges have values +2Q, -Q, and +Q, as shown, where Q = 7 μC. What is the y-component of the force on the charge +2Q? a. F = -1.14 N b. F = 4.77 N c. F = -1.76 N d. F = -4.77 N e. F = -2.28 N What is the work required to create...

We study the three point charges shown in the figure. They are held at the corners of an equilateral triangle with ℓ = 0.7 m. What is the electric potential energy (in J) of the system of three point charges? Use for the three charges q1 = +2Q, q2 = −3Q, and q3 = +Q, where Q = 104 nC. Hint: The solution is done in steps. Assume that you first bring one of the point charges from a very...

Initially, identical point charges (+12 UC) are placed at the corners of an equilateral triangle with sides of 2.0 m length. Next, a 50. UC charge is brought from very far away and placed at the midpoint of the bottom side of the triangle. How much work is done by the field to bring that charge of 50. UC from infinity to the midpoint of the bottom side of the triangle? - 9.3 - 14 19 26 - 23
