(Solved): the question is very clear and there is nothing to add. it is already completed so answer it corectl ...

1) An electron moves through a uniform electric field \( \overrightarrow{\mathbf{E}}=(2.90 \hat{\mathbf{i}}+4.90 \mathbf{j}) \mathrm{V} / \mathrm{m} \) and a uniform magnetic field \( \overrightarrow{\mathbf{B}}=0.400 \hat{\mathrm{K}} T \). Determine the acceleration of the electron when it has a velocity \( \vec{v}=8.0 \mathbf{i} \mathrm{m} / \mathrm{s} \). (Give each component in \( \mathrm{m} / \mathrm{s}^{2} \).) \[ \begin{array}{ll} a_{x}= & \mathrm{m} / \mathrm{s}^{2} \\ a_{y}= & \mathrm{m} / \mathrm{s}^{2} \\ a_{z}= & \mathrm{m} / \mathrm{s}^{2} \end{array} \] What If? For the electron moving along the \( x \)-axis in the fields in part (a), what speed (in \( \mathrm{m} / \mathrm{s} \) ) would result in the electro also experiencing an acceleration directed along the \( x \)-axis? \[ \mathrm{m} / \mathrm{s} \] mes
