The angular momentum of a particle relative to a certain point varies

1.	The angular momentum of a particle relative to a certain point varies with time as L=a-bt^(2) , where a and b are Constant vectors, with abotb. Find the force moment tau relative to the point O acting on the particle when the angle between the vectors tau and Lequals 45^(@)
Answer» SOLUTION :`tau=2bsqrt((a)/(B))`
