Q61
A classical particle is moving in an external potential field V(x, y, z) which is invariant under the following infinitesimal transformations \[ array*20c x x'& = &x + x \\ y y'& = &y + y \\ [ array*20c x \\ y array ] [ array*20c x' \\ y' array ]& = &R_z [ array*20c x \\ y array ] array\] where, Rz is the matrix corresponding to rotation about the Z-axis. The conserved quantities are (the symbols have their usual meaning)
