A particle of mass $\displaystyle m$ and charge $\displaystyle q$ 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 $\displaystyle \mathrm{P}(x=1 ; y=1)$ along a straight path. The magnitude of the total work done is :
