5. What is the path of a charged particle moving perpendicular to a uniform magnetic field?

Circular
Straight line
Parabolic
Helical

6. What is the Lorentz force formula for a charge moving in a magnetic field?

F = qvB cosθ
F = qvB sinθ
F = qvB
F = qE

7. Which rule gives the direction of force on a moving charge in a magnetic field?

Left-hand rule
Right-hand rule
Cork screw rule
Fleming's right-hand rule

8. What is the magnetic force on a charge moving parallel to a uniform magnetic field?

Maximum
Zero
Half of maximum
Depends on speed

9. What equation gives the radius of the circular path of a charged particle in a magnetic field?

qvB = mv²/r
qvB = mv/r
qvB = mrω²
qvB = ma

10. What is the radius of a charged particle in a perpendicular magnetic field?

r = mq/(vB)
r = mv/(qB)
r = qB/(mv)
r = mvB/q
