Q7.10Multiple correct
Figure 7.4 shows two identical particles 1 and 2, each of mass m, moving in opposite directions with same speed v along parallel lines. At a particular instant, r1 and r2 are their respective position vectors drawn from point A which is in the plane of the parallel lines . r1 Choose the correct options: d1
This question refers to a figure in the original PDF.
- (a)Angular momentum l1 of particle 1 about A is l1 = mvd1 1 v d2
- (b)Angular momentum l2 of particle 2 about A is l2 = mvr2 r2
- (c)Total angular momentum of the system about A is l = mv(r1 + r2 ) v 2
- (d)Total angular momentum of the system about A is l = mv(d 2 − d1 ) ⊗ Fig. 7.4 represents a unit vector coming out of the page. ⊗ represents a unit vector going into the page.
