JEE Main Physics question
A particle of mass is travelling with a constant velocity along the line , . Let be the area swept out by the position vector from the origin to the particle, in time , and be the magnitude of the angular momentum of the particle about the origin at any time . Then
Answer: (A),(D)
Solution
Straight-line uniform motion at fixed perpendicular distance from the origin gives constant — (A) is correct. The area swept rate for any
