The angular momentum (M) of a particle relative to a certain point (O), varies with time as vec(M)=vec(a)+vec(b)t^(2) where vec(a) and vec(b) are constant vectors and vec(a) is perpendicular to vec(b). The moment of the force (N) relative to the point O, acting on the particle, when N makes 45^(@) with M is xbsqrt(a//b). Find the value of x ?

The angular momentum (M) of a particle relative to a certain point (O)

1.	The angular momentum (M) of a particle relative to a certain point (O), varies with time as vec(M)=vec(a)+vec(b)t^(2) where vec(a) and vec(b) are constant vectors and vec(a) is perpendicular to vec(b). The moment of the force (N) relative to the point O, acting on the particle, when N makes 45^(@) with M is xbsqrt(a//b). Find the value of x ?
