Concept explainers
Speed of electron.
Answer to Problem 21P
The answer is
Explanation of Solution
Given:
Charges
Radius,
Mass,
Formula used:
Because of conservation of energy, all of initial potential energy is converted to kinetic energy (at the time when the charges are far apart). No charge is fixed.Hence, both are moving at the same speed away from each other. So,
Where,
Calculation:
Substitute all the known and given values in expression
Conclusion:
The required speed is
