Question:
An electron and a proton are moving parallel to each other and to the magnetic field. The magnetic force acting on the proton is:
Options:
Less than electron
More than electron
Zero
1840 times more than electron
Correct Answer:
Zero
Explanation:
A magnetic field does not exert any force on a charge moving parallel or antiparallel to the field direction. Since they are traveling in the direction of the magnetic field, there will be no force acting on them. Hence their paths will remain the same after entering the magnetic field.
