The Electric Potential Along the X-Axis Is V=100E−2XV Where X Is in Meters
Electric potential is a fundamental concept in physics that helps us understand the behavior of electric fields. In this article, we will explore the electric potential along the X-axis, specifically given by the equation V = 100e^(-2x) V, where x is measured in meters.
The equation V = 100e^(-2x) V represents a decreasing exponential function of x. As x increases, the electric potential decreases exponentially. Let’s take a closer look at this equation and its implications.
The presence of the exponential term e^(-2x) indicates that the electric potential diminishes rapidly as x increases. The constant 100 determines the initial potential value at x = 0, which is 100V. As x increases, the exponential term decreases, causing the potential to decrease.
Now, let’s address some common questions related to this topic:
