PhysicsEasysingle choice

Two particles $A$ and $B$ are moving, as shown in the figure.

Their total angular momentum about the point $O$ is

Options:

Answer:

Solution:

Total angular momentum about O is given as,

$\vec{L} = {\vec{L}}_{1} + {\vec{L}}_{2} = - m_{1} v_{1} r_{1} + m_{2} v_{2} r_{2}$ (anti clockwise)

$= - 6.5 \times 2.2 \times 1.5 + 3.1 \times 3.6 \times 2.8$ (anti clockwise)

$= - 21.45 + 31.248 = 9.8 kg \cdot m^{2} \cdot s^{- 1}$ (anti clockwise)
