20.3 The position x of particle moving along x-axis varieswith time t as x-Asin (dot) where A and ω arepositive constants. The acceleration a of particlevaries with its position (x) as(1) a=Ax(3) a = A ωχ(2) a _ω3x(4) a 02 x A |

Answer» After double differentiating the given equation we get the acceleration ,i.e d²x/dt²=A(w²)×-sin(wt) =-(w²)×Asin(wt)But we know that Asin(wt) =x,Therefore, answer is a=-w²x |
