A and B are two properly working identical wall clocks. A is hung on Eastern wall and B is hung on Northern wall of a room. The magnitude of angular velocity of seconds hand of A relative to that of B(in Rad/sec) is? a)Pi/30(Root 2) b)Pi/30 c)[(root 2)Pi]/30 d)2(root2)Pi/30 Plz explain..

C........Cool

the angular velocity of east clock points in west,that of b points in south. let west direction be i & south direction be j.

so wa-wb=wi-wj

thus its magnitude =root2xw

w=2pi/60=pi/30

ans=(root2xpi)/30
