Problem 35PE
Unreasonable Results
(a) What is the final speed of an electron accelerated from rest through a voltage of 25.0 MV by a negatively charged Van de Graaff terminal?
(b) What is unreasonable about this result?
(c) Which assumptions are responsible?
Solution 35PE
- 2.96 x 109 m/s
- The speed of the electron calculated is very high even high than the speed of light. The speed is unreasonable.
- The speed of the electron should be calculated with relativistic approach.
