Question

Assume that you have a configuration of conductors with varying electric potentials applied to each, such as you will be dealing with in this lab. You make the following measurements of the values of the electric potential at different points in a dimensional grid: X = 0.00 cm Y = 0.0 cm V = 2.0 volts X = 0.00 cm Y = 0.00 cm V = 2.25 volts X = 0.00 cm Y = 0.00 cm V = 2.0 volts What are the values of the x and y components of the electric field at the origin (E_x and E_y at (x, y) = (0, 0))? Express the results in SI units. For help on doing this problem, read question 1 -6 in this lab writeup.

Explanation / Answer

we know, E = -dV/dr

so, Ex = -dV/dx

Ex = -(V2x - V1x)/(x2 - x1)

= -(2.25 - 2)/(0.02 - 0)

= -12.5 N/c <<<<<<<<<<-------------Answer

and
Ey = -dV/dy

Ey = -(V2y - V1y)/(y2 - y1)

= -(2 - 2)/(0.02 - 0)

= 0 N/c <<<<<<<<<<-------------Answer
