Moving Charges And Magnetism

A proton is projected with velocity \(\mathbf{v}=2 \hat{\mathbf{i}}\) in a region where magnetic field \(\mathbf{B}=(\hat{\mathbf{i}}+3 \hat{\mathbf{j}}+4 \hat{\mathbf{k}}) \mu \mathrm{T}\) and electric field \(\mathbf{E}=10 \hat{\mathbf{i}} \mu \mathrm{V} / \mathrm{m}\). Then find out the net acceleration of proton
