An electron enters an electric field having intensity E=3i^+6j^+2k^Vm1\vec{E} = 3\hat{i} + 6\hat{j} + 2\hat{k}\,\text{Vm}^{-1} and magnetic field having induction B=2i^+3j^T\vec{B} = 2\hat{i} + 3\hat{j}\,\text{T} with a velocity v=2i^+3j^ms1\vec{v} = 2\hat{i} + 3\hat{j}\,\text{ms}^{-1}. The magnitude of the force acting on the electron is (Given, e=1.6×1019Ce = -1.6 \times 10^{-19}\,\text{C})
