Question

З яким прискоренням рухається електрон у полі напруженість якого становить 5 кВ/м?

Answer 1

Сила:
F = E*e  
Ускорение:
a = F / m = E*e / m               (1)

Здесь:
E = 5 кВ/м = 5*10³ В / м  -  напряженность поля
e = 1,6*10⁻¹⁹ Кл - заряд электрона
m = 9,1*10⁻³¹ кг - масса электрона.

Подставляем данные в формулу (1)
a = 5*10³*1,6*10⁻¹⁹ / 9,1*10⁻³¹ ≈ 9*10¹⁴ м/с²

Answer 2

Calculating the Acceleration of an Electron in an Electric Field

To calculate the acceleration of an electron in an electric field, we can use the formula:

a = eE/m

Where: - a = acceleration - e = elementary charge (approximately 1.6 x 10^-19 C) - E = electric field strength (given as 5 kV/m, which is equivalent to 5000 V/m) - m = mass of the electron (approximately 9.11 x 10^-31 kg)

Calculation

Substituting the given values into the formula:

a = (1.6 x 10^-19 C) * (5000 V/m) / (9.11 x 10^-31 kg)

Result

The acceleration of the electron in the electric field with a strength of 5 kV/m is approximately 8.78 x 10^14 m/s^2.
