Answer:
Correct Answer: 25. (c)
Solution:
- For particle to move in negative $y$-direction, either its velocity must be in negative $y$-direction (if initial velocity $\neq 0$ ) and force should be parallel to velocity or it must experience a net force in negative $y$-direction only (if initial velocity $=0$ )
