Question
If the electric potential along the x-axis is V, where x is in meters, what is at m?
-
- V/m
- -250. V/m
- -500. V/m
-
- V/m
Solution
The electric field E is related to the potential V by the equation E = -dV/dx, where dV/dx is the derivative of the potential with respect to position.
Given V = 500x^2, we can differentiate this with respect to x to find the electric field.
dV/dx = 2500x = 1000x
Substituting x = 0.500 m into this equation gives:
E = -dV/dx = -1000*0.500 = -500 V/m
So, the electric field Ex at x = 0.500 m is -500 V/m.
