1) A particle moves along a straight line parallel to the x-axis at a constant velocity, Its angular momentum about the origin?
2) Can a free electron moves from higher potential to low potential?
3) Progressive wave carries energy in a plane perpendicular to the plane wave front-is the statement true?
4) Why a heavier body doesn’t fall more quickly than a lighter body?
5) Is it possible to transfer electic charge from a body of a lower potential to a higher potential?
