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