When a charged particle moves perpendicular to a uniform magnetic field, then
- A its momentum changes and total energy is same
- B Both momentum and its total energy remain the same
- C Both momentum and its total energy will change
- D total energy changes but momentum remains same
Answer & Solution
Correct Answer
(A) its momentum changes and total energy is same
Step-by-step Solution
Detailed explanation
When a charged particle moves in a uniform magnetic field normally, then a magnetic force acts on it. Due to this force, it will move in a circular path. At every point of circle, its velocity changes direction. So, its mumentun also changes bul the Lotal energy will remain same.
