177. The displacement x of a particle varies with time t as, x = ae-αt +b e βt where a, b α and β are positive constants. The velocity of the particle will
D. go on increasing with time x = a e αt +b e βtSo velocity v = dXdt =-a αe-αt + b βe βeν = A + BWhere A = -a αe-αt , B =b βe βr The value of term A = a e-αt decreases and of term B = b βeβe increases with increase in time. As a result, velocity goes on increasing with time. Open in App Suggest Corrections 0 |
