A uniform electric field $\mathrm{E}=(8 \mathrm{~m} / \mathrm{e}) \,\mathrm{V} / \mathrm{m}$ is created between two parallel plates of length $1 \mathrm{~m}$ as shown in figure, (where $\mathrm{m}=$ mass of electron and e = charge of electron). An electron enters the field symmetrically between the plates with a speed of $2 \mathrm{~m} / \mathrm{s}$. The angle of the deviation $(\theta)$ of the path of the electron as it comes out of the field will be _________.
