Which of the following property of a proton can change while it moves freely in a magnetic field? (There may be more than one correct answer.) 1. Mass 2. Speed 3. Velocity 4. Momentum
ScienceClass 10CBSEAnswered 27 Mar 2026
Answer
(c) and (d)
When a proton enters the region of a magnetic field, it experiences a magnetic force. Due to this, the path of the proton becomes circular. As a result, the velocity and the momentum change.
