Question

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.)

विकल्प

• mass

• speed

• velocity

• momentum

Answer 1

velocity and momentum

Explanation:

Every charged particle moving in a magnetic field experiences a force. Fleming's left-hand rule determines the direction of the force on a positively charged particle (such as a proton). This force will alter both the velocity and momentum of the proton.
