3-2.Motion in Plane
medium
Velocity of two particles $A$ and $B$ separated by distance $20\ m$ apart is as shown in figure then ........ $rad/s$ will be the angular velocity of $B$ with respect to $A$
A
$4.75$
B
$8.75$
C
$16.75$
D
None of these
Solution
Componet of Linear velocity of $B$
$\mathrm{W}_{\mathrm{BA}}=\frac{\text { with respect to AWhich is prependicular to } \overrightarrow{\mathrm{AB}}}{|\overrightarrow{\mathrm{AB}}|}$
$=\frac{100 \sqrt{3} \sin 60^{\circ}-50 \sin 30^{\circ}}{20}$
