Q1
A proton moves in a magnetic field and experiences a force. If the velocity of the proton is doubled, what happens to the magnetic force?
It doubles
It halves
It remains the same
It quadruples
The magnetic force is proportional to the velocity of the charge, so if the velocity is doubled, the magnetic force also doubles.

Q
Q: A proton moves in a magnetic field and experiences a force. If the velocity of the proton is doubled, what happens to the magnetic force?
Solution: The magnetic force is proportional to the velocity of the charge, so if the velocity is doubled, the magnetic force also doubles.
Steps: 6
Step 1: Understand that a proton is a charged particle.
Step 2: Know that when a charged particle moves in a magnetic field, it experiences a magnetic force.
Step 3: Remember the formula for magnetic force: F = q * v * B, where F is the force, q is the charge, v is the velocity, and B is the magnetic field strength.
Step 4: Identify that in this formula, the force (F) is directly proportional to the velocity (v) of the proton.
Step 5: If the velocity (v) of the proton is doubled, then the magnetic force (F) will also double.
Step 6: Conclude that if the velocity of the proton is doubled, the magnetic force it experiences will also double.
