Four charges of equal charge+q are placed at the corners of a rectangle of sides a and b. What is the potential at the center of the rectangle if q = 2.0 uc, a = 3.0 cm, and b = 4.0cm?​

V = 32.2 10³ V

Explanation:

The electric potential is a scalar quantity given by the expression

          V = h ∑  

Let's find the distance from each corner to the center of the square, using Pythagoras' theorem

           r =

indicate that all charges have the same magnitude and the casticista from each scheme to the center is r

           V = k q ()

let's calculate

            r = ½ Ra 2² + 4²

            r = 2,236 m

           V = 9 10⁹ 2 10⁻⁶  4 / 2,236

           V = 32.2 10³ V

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
