An evacuated tube uses an accelerating voltage of 50 kV to accelerate electrons to hit a copper plate and produce X-rays. Non-relativistically, what would be the maximum speed (in m/s) of these electrons

Respuesta :

Answer:

Explanation:

Accelerating voltage = 50 x 10Ā³ V

energy created = q V where q is charge on electron and V is accelerating potential

So qV = 1/2 m vĀ² , m is mass of electron and v is velocity

Putting values

1.6 x 10ā»Ā¹ā¹ x 50 x 10Ā³ = 1/2 x 9.1 x 10ā»Ā³Ā¹ x vĀ²

vĀ² = 175.8 x 10Ā¹ā“

v = 13.25 x 10ā· m /s
