SUMMARY
The electric potential along the x-axis is defined by the equation V=100e^(−2x/m), where x is measured in meters. To find the electric field Ex at specific points, the derivative of V with respect to x is calculated, yielding Ex = (-200/m)e^(-2x/m). The variable m represents a unit of measurement, specifically indicating that the 2 in the exponent has units of 1/m. By assuming m=1, the correct values for Ex at x=1.0m and x=2.1m can be determined.
