Two particle A and B are moving as shown in the figure Their total

1.	Two particle A and B are moving as shown in the figure Their total angular momentum about the point O is
Answer» `9.8 kg m^(2) s^(-1)` ZERO `52.7 kg m^(2) s^(-1)` `37.9 kg m^(2) s^(-1)` Solution :Total angular momentum about O is GIVEN as, `L=L_(1)+L_(2)=m_(1)v_(1)r_(1)+m_(2)v_(2)r_(2)` `=-6.5 xx2.2xx1.5+3.1xx3.6 xx2.8` `=-21.45 + 31.248 = 9.8 "KGM"^(2) s^(-1)`.
