The tangenital acceleration of a particle in a circular motion of radius 2 m is `a_(t)=alphat m//s^(2)` (where `alpha` is a constant) initially the particle as rest. Total acceleration of the particle makes `45^(@)` with the radial acceleration after 2 sec The value of constant `alpha` is :A. `1/2 m//s^(3)`B. `1 m//s^(3)`C. `2 m//s^(3)`D. Data are insufficient |
