- AEnergy decreases
- BEnergy increases
- CMomentum increases
- ✓Momentum and energy remain unchanged
✓
Answer
Correct option: D.
Momentum and energy remain unchanged
d
(d)Since force is perpendicular to direction of motion. energy and magnitude of momentum remains constant.
(d)Since force is perpendicular to direction of motion. energy and magnitude of momentum remains constant.
