A particle of mass $m$ and charge $q$ is in an electric and magnetic field given by $$\overrightarrow { \mathrm { E } } = 2 \hat { i } + 3 \hat { j } ; \overrightarrow { \mathrm { B } } = 4 \hat { j } + 6 \hat { k }$$ The charged particle is shifted from the origin to the point $\mathrm { P } ( x = 1 ; y = 1 )$ along a straight path. The magnitude of the total work done is:
(1) (0.35)q
(2) $5 q$
(3) $( 2.5 ) q$
(4) $( 0.15 ) q$
