The potential energy of a particle varies with distance $x$ as shown in the graph. The force acting on the particle is zero at

$A$ particle of mass $m$ with initial kinetic energy $K$ approaches the origin from $x = +\infty$. Assume that a conservative force acts on it and its potential energy $V(x)$ is given by $V(x) = \frac{K}{\exp(3x/x_0) + \exp(-3x/x_0)}$, where $x_0 = 1 \ m$. The speed of the particle at $x = 0$ is

What are conservative force,non-conservative force,conservative field,and non-conservative field?

The potential energy graph of a particle is given. Find the corresponding force graph.

The potential energy of a system increases if work is done
