Three particles A, B, Care located at the comers of an equilateral triangle as shown in figure. Each of the particle is moving with velocity v. Then at the instant shown, the relative angular velocity of
A. `A wrt. B "is"=(v cos 30^(@))/(a)" in z-direction"`
B. `B wrt. C "is"=(v cos 30^(@))/(a)" in z-direction"`
C. `A wrt. C "is"=(v cos 30^(@))/(a)" in z-direction"`
D. `B wrt. A "is"=(v cos 30^(@))/(a)" in z-direction"`
