According to the x-axis, the electric potential is given by V = 200x2V, where x is measured in meters. What is the value of Ex when x =0m?

Your answer should be expressed as an integer with the appropriate units included in your answer

**SOLUTION:**

- E = -dV(x)/dx, the derivative of V is -400x V/m, and the derivative of x is -400x V/m.
- E(0) = -400(0) V/m = 0 V/m E(0) = -400(0) V/m

**PART B:**

What is the value of Ex when x =3m?

Include the appropriate units in your answer and three significant figures in your response.

**SOLUTION:**

E = -dV(x)/dx, the derivative of V is -400x V/m, and the derivative of x is -400x V/m.

E(3) = -400(3) V/m = -1200 V/m = -1.20103 V/m E(3) = -400(3) V/m = -1200 V/m
