A particle of mass m is travelling with a constant velocity vec(v)=v_(0)hat(i) along the line y=b,z=0 Let dA be the area swpt out by the position vector from origin to the particle in time dt and L the amgnitude of angular momentum of particle about origin at any time t. Then (dA)/(dt)=(L)/("xm") where 'x' is |
