Question
When a charged particle moves at right angle to a magnetic field quantity that changes is:
✓
Answer
Momentum
Explanation:
When a charged particle moves perpendicular to the field, its speed remains the same whereas its velocity keeps on changing.
Momentum is the product of the mass of the particle and the velocity if the particle, hence since velocity varies, momentum also varies.
When a charged particle moves at right angle to a magnetic field quantity that changes is momentum.
