An electron that has an instantaneous velocity of $$ \vec{v}=\left(2.0 \times 10^{6} \mathrm{m} / \mathrm{s}\right) \hat{\mathrm{i}}+\left(3.0 \times 10^{6} \mathrm{m} / \mathrm{s}\right) \hat{\mathrm{j}} $$ is moving through the uniform magnetic field $\vec{B}=(0.030 \mathrm{T}) \hat{\mathrm{i}}-$ $(0.15 \mathrm{T}) \hat{\mathrm{j}} .(\mathrm{a})$ Find the force on the electron due to the magnetic field. (b) Repeat your calculation for a proton having the same velocity.
