QAIPMT-2007-Ph-2335: NEET 2007 Physics - Class 11 AIPMT-2007-Ph-2335 Solution: A particle of mass m moves in the XY plane with a velocity v…
A particle of mass m moves in the XY plane with a velocity v along the straight line AB. If the angular momentum of the particle with respect to origin O is when it is at A and when it is at B, then
Multiple Choice Options
- A
- B the relationship between and depends upon the slope of the line AB
- C
- D
Step-by-Step Verified Solution
Angular momentum = Linear momentum _
perpendicular distance between line of action of
liner momentum from origin
Let d be the perpendicular distance.
p A and p B be the linear momentum at A and B
Angular momentum L A = p A _ d
L B = p B _ d
So, linear momentum will be equal, i.e., L A = L B .here,
p A and p B are equal as have equal velocity.
L A = L B
