Chapter 5.2, Problem 1PE

Interpretation Introduction

Interpretation: The velocity of ${\text{A}}^{+}$ charge (slower) by which it should move to equal the kinetic energy of ${\text{B}}^{+}$ is to be calculated.

Concept introduction: The kinetic energy $\left(\text{K}\text{.E}\right)$ of a particle is calculated by the formula,

$\text{K}\text{.E}=\frac{1}{2}m{v}^2$

To determine: The velocity of ${\text{A}}^{+}$ charge (slower) by which it should move to equal the kinetic energy of ${\text{B}}^{+}$.
