A vector has components `p` and 1 with respect to a rectangular Cartesian system. The axes are rotted through an angel `alpha`about the origin the anticlockwise sense. Statement 1: IF the vector has component `p+2`and 1 with respect to the new system, then `p=-1.` Statement 2: Magnitude of the original vector and new vector remains the same.
