Question

Incorrect. Eqvation 21.1 shows the magnetic force on a moving charge depends on the angle between the charge's velocity vector and the magnetic fieid The figure shows three identical charged particles meving with the same speed but at different directions in a uniform magnetic field. Rank the charges in order of the magnetic force each one experiences starting with the largest 123 1, 2, 3 3,2,

Answer 1

2,1,3 (second option)

explanation

We know that the magnetic force is given by

F = q v B sin(theta)

for 3, v is parallel to B so theta = 0

F3 = 0

For 2, theta = 90 deg

F = q v B

for 1, theta = 45 or any other value, so it will be less than q v B

So the order (largest to smallest)

2, 1 , 3
