নিচের কোনটি লরেঞ্জ বলের রাশিমালা?

$\overrightarrow{\mathrm{F}}=\mathrm{q} \overrightarrow{\mathrm{E}}$

$\overrightarrow{\mathrm{F}}=\mathrm{q} \overrightarrow{\mathrm{E}}+\mathrm{q}(\overrightarrow{\mathrm{v}} \times \overrightarrow{\mathrm{B}})$

$\rm{\overrightarrow{F}=q(\overrightarrow{v} \times \overrightarrow{B})}$

$\rm{\overrightarrow{F}={q \widehat{v} B} \sin \widehat{n}}$
