Electric potential V versus position x along the x-axis.
Electric potential V versus position x along the x-axis.
A particle with charge \(q = +2.0 \text{ } \mu\text{C}\) is constrained to move along the \(x\)-axis in a region of electric potential \(V(x)\), as shown in the graph. The graph features a local potential minimum of \(V = 10 \text{ V}\) at \(x = 2.0 \text{ cm}\), bounded by a potential peak of \(V = 50 \text{ V}\) at \(x = 0.0 \text{ cm}\) to the left and a potential peak of \(V = 40 \text{ V}\) at \(x = 5.0 \text{ cm}\) to the right. What is the maximum kinetic energy the particle can have at \(x = 2.0 \text{ cm}\) such that it remains bound within the potential well near \(x = 2.0 \text{ cm}\)?
