Question

In: Physics

On a graph, there are 7 positive charges (each being +1 nC). The position are all along the x-axis (y=0) at x=-1.5m, -1.0m, -0.5m, 0m, 0.5m, 1.0m, and 1.5m.

On a graph, there are 7 positive charges (each being +1 nC). The position are all along the x-axis (y=0) at x=-1.5m, -1.0m, -0.5m, 0m, 0.5m, 1.0m, and 1.5m. Meanwhile, a sensor (aka point P) is above the charges at position (0, 0.5m). Draw the electric field using Coulomb's Law at point P (the sensor). The sensor is 69.4 V/m and direction is 90 degrees.
