Three examples from the live 100-question bank. Answers appear after attempting them in practice mode.
Example 1 · difficulty 1/5
A proton moving horizontally at 2.0×10⁶ m s⁻¹ enters a region where a uniform magnetic field of 0.50 T acts vertically upward, the velocity being perpendicular to the field. Taking the proton charge as 1.6×10⁻¹⁹ C, the magnitude of the instantaneous magnetic force on the proton is:
- A. 1.6×10⁻¹³ N
- B. 8.0×10⁻¹⁴ N
- C. 3.2×10⁻¹³ N
- D. zero, because the magnetic force can do no work on the charge
Example 2 · difficulty 2/5
A charged particle projected with speed v perpendicular to a uniform magnetic field B moves in a circle of radius r. The experiment is repeated in a field of strength B/2 with the projection speed changed to 2v, everything else remaining the same. The radius of the new circular path is:
- A. r/2
- B. 2r
- C. 4r
- D. r (unchanged)
Example 3 · difficulty 2/5
In a velocity selector, a uniform electric field of 3.0×10⁴ V m⁻¹ and a uniform magnetic field of 0.60 T are applied mutually perpendicular. A positively charged particle passes through the region undeflected. Its speed is:
- A. 1.8×10⁴ m s⁻¹
- B. 5.0×10⁴ m s⁻¹
- C. 2.0×10⁻⁵ m s⁻¹
- D. 5.0×10⁵ m s⁻¹
