Question

The displacement x of a particle varies with time t as x = ae^-αt + be^βt, where a, b, α and β are positive constants. The velocity of the particle will

(a) be independent of β

(b) drop to zero when α  =  β

(c) go on decreasing with time

(d) go on increasing with time.

Answer 1

Correct option (d) go on increasing with time.

Explanation:

For certain value of t, velocity will increases.
