Chapter 5.1, Problem 1PE

Interpretation Introduction

Interpretation: The comparison between the speeds of the given charged particles ${\text{A}}^{+}$ and ${\text{B}}^{+}$ corresponding to their kinetic energies being equal is to be stated.

Concept introduction: The kinetic energy of the particle is the amount of energy that it possesses due its own movement. The kinetic energy of a particle is calculated by,

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

To determine: The velocity of the positively charged particle ${\text{A}}^{+}$ that is required to become equals to the kinetic energy of ${\text{B}}^{+}$ particle.
