a.
To calculate: If the ratio
a.
Answer to Problem 63A
Explanation of Solution
Given:
The J.J. Thomson’s cathode ray tube is modified to accelerate protons rather than electrons.
Formula used:
Velocity is given by,
Where
Calculation:
Since particles of the same velocity are to be selected, the
Hence, it is obvious that if velocity will be the same,
Conclusion:
b.
To calculate: If
b.
Answer to Problem 63A
For the deflection to remain the same, magnetic field strength needs to be larger.
Explanation of Solution
Given:
The J.J. Thomson’s cathode ray tube is modified to accelerate protons rather than electrons.
Formula used:
Magnetic force is given by,
Where
Calculation:
The deflection caused by the magnetic field is calculated as:
For a larger mass,
Conclusion:
For the deflection to remain the same, magnetic field strength needs to be larger.
