Question

in an oblique impact the component of velocity of a particle perpendicular to the line of impact 1] remain same after impact 2]increase after the impact 3] decrease after the impact explain this answer??

Answer 1

I think so. Because the impulse \(\Delta \vec p =\vec F \Delta t\) will be along the line of impact

Answer 2

that is absolutely correct sir

Answer 3

1}Since there is no force acting on object in direction perpendicular to line of impact , the momentum remains conserved i.e. velocity remains same.
