At what intensity of a uniform electric field the electron moves with acceleration g = 9.8 m / s ^ 2.
| September 6, 2021 | education
Task data: a (acceleration with which the electron should move) = 9.8 m / s2.
Constants: qe (electron charge) = -1.6 * 10-19 C; me (mass of one electron) = 9 * 10-31 kg.
To calculate the required field strength, we use the formula: qe * E = m * a, whence E = m * a / qe.
Let’s calculate: E = 9 * 10-31 * 9.8 / (1.6 * 10-19) = 55.125 * 10-12 V / m = 55.125 pV / m.
Answer: The required field strength is 55.125 pV / m.
