Two plates separated by a distance \( d=13.3 \mathrm{~mm} \) are charged to a potential difference \( V=7.25 \mathrm{~V} \). A constant force \( F=8.81 \mathrm{~N} \) pushes a -8.30 mC charge from the positively charged plate to the negatively charged plate. Calculate the change in the kinetic energy \( \Delta K \), potential energy \( \Delta U \), and total energy \( \Delta E \) of the charge as it travels from one plate to the other. Assume the initial speed of the charge is 0 . \[ \Delta K=\square \] J \( \square \) \[ \begin{array}{l} \Delta U=\square \mathrm{J} \\ \Delta E=\square \mathrm{J} \end{array} \]
