A) energy and momentum both remains constant
B) energy remains constant but momentum changes
C) both energy and momentum changes
D) energy changes but momentum remains constant
Correct Answer: B
Solution :
When charge particle enters in a magnetic field perpendicularly, then the magnitude of its velocity remains constant, but direction changes, so its energy (scalar quantity) remains constant, but its momentum (vector quantity) changes.You need to login to perform this action.
