The radius vector of a particle varies with time t as vecr=vecbt(1-alpha t)where vecbis a constant vector and a is a positive factor . Find the time interval Delta ttaken by the particle to return to the initial point

The radius vector of a particle varies with time t as vecr=vecbt(1-alp

1.	The radius vector of a particle varies with time t as vecr=vecbt(1-alpha t)where vecbis a constant vector and a is a positive factor . Find the time interval Delta ttaken by the particle to return to the initial point
Answer» SOLUTION :`vecr=vecbt(1-alpha t)` For INITIAL POINT , `vecr=0,vecb=t(1-alphat)=0` `t=0"and" t=1/alpha` HENCE,` Deltat=1/alpha `
