What is Lorentz force? Write an expression for it.

Question

$\begin{array}{1 1} (a)\;\overrightarrow{F}=q(\overrightarrow{B}+\overrightarrow{v} \times \overrightarrow{E})\\ (b)\;\overrightarrow{F}=q(\overrightarrow{E}+\overrightarrow{v} \times \overrightarrow{B}) \\ (c)\;\overrightarrow{F}=q(\overrightarrow{E}-\overrightarrow{B} \\\ (d)\;\overrightarrow{F}=q(\overrightarrow{E}+\overrightarrow{B})\end{array}$
