Q. What is the force experienced by a current-carrying conductor of length L in a magnetic field B at an angle θ? (2023)
A.
F = BIL
B.
F = BIL sin(θ)
C.
F = BIL cos(θ)
D.
F = BIL²
Solution
The force on a current-carrying conductor in a magnetic field is given by F = BIL sin(θ), where θ is the angle between the conductor and the magnetic field.
Q. What is the force on a charge moving in a magnetic field given by F = qvB sin(θ)? (2022)
A.
It is always zero
B.
It depends on the angle θ
C.
It is constant
D.
It is maximum when θ = 90°
Solution
The force on a charge moving in a magnetic field is maximum when the angle θ between the velocity vector and the magnetic field is 90°, as sin(90°) = 1.
Q. What is the force on a charge moving in a magnetic field given by the equation F = qvB sin(θ)? (2020)
A.
Charge times velocity
B.
Charge times magnetic field
C.
Charge times velocity times magnetic field times sine of angle
D.
Charge times sine of angle
Solution
The force on a charge moving in a magnetic field is given by F = qvB sin(θ), where q is the charge, v is the velocity, B is the magnetic field strength, and θ is the angle between the velocity and the magnetic field.
Correct Answer:
C
— Charge times velocity times magnetic field times sine of angle
