The displacement x of a particle varies with time t as \(x=a e^{-a t}+b e^{k}\), where a, b, \(\alpha\)and \(\beta\) are positive constants. The velocity of the particle will:
- go on decreasing with time
- be independent of \(\alpha\) and \(\beta\)
- drop to zero when \(\alpha=\beta\)
- go on increasing with time
Answer
(D) go on increasing with time
