The magnitude of the electron's acceleration can be calculated using the formula $a = \frac{F}{m}$, where $F$ is the force acting on the electron and $m$ is the mass of the electron.

However, to provide the exact value of the electron's acceleration, the force applied on the electron needs to be known. If the force is provided, I can compute the acceleration.

Please provide the necessary details, or clarify if there's a specific scenario or context for which this calculation is needed.
