Concept explainers
Choose the correct option from the given choices to identify the statement that is not true about the electric force and magnetic force.
Answer to Problem 1RQ
The correct options from the given choices are (b) Both Fe and Fm depend on the velocity of the charged particle and (c) Both Fe and Fm can perform work.
Explanation of Solution
Calculation:
Write the general expression for electric force.
Here,
Write the general expression for the magnetic force.
Here,
u is the velocity,
On observing Equation (2), the magnetic force
From Equation (2), it is clear that the magnetic force
From the above explanation, it is clear that Options (b) and (c) are correct and Options (a), (d), (e), and (f) are incorrect.
Conclusion:
Thus, the correct options from the given choices are (b) Both Fe and Fm depend on the velocity of the charged particle and (c) Both Fe and Fm can perform work.
