AIPMT 2007 | Rotational Motion Question 64 | Physics

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 L_A when it is at A and L_B when it is at B, then AIPMT 2007 Physics - Rotational Motion Question 47 English

AIPMT 2007 Physics - Rotational Motion Question 47 English
