Question

What is the kinetic energy of the -6 μC charge after it has moved to a distance of 12.4 cm away from the 4.8 μC charge?

Expert Solution

Step 1 :Introduction

According to the law of conservation of energy , energy can neither be created nor destroyed but can only be converted from one form to another . Thus the kinetic energy is calculated by using the formula $E = \frac{k q_{1} q_{2}}{2 r}$ , where $k = 9 \times 10^{9} N m^{2} / C^{2}$ is the Coulomb's law , $q_{1} = - 6 \times 10^{- 6} C$ and $q_{2} = 4.8 \times 10^{- 6} C$ are the charges and $r = 0.124 m$ is the distance between the charges .
