Kinematics Question 1
Question: There are two force vectors, one of 5 N and other of 12 N at what angle the two vectors be added to get resultant vector of 17 N, 7 N and 13 N respectively
Options:
A) $ 0{}^\circ $ , $ 180{}^\circ $ and $ 90{}^\circ $
B) $ 0{}^\circ $ , $ 90{}^\circ $ and $ 180{}^\circ $
C) $ 0{}^\circ $ , $ 90{}^\circ $ and $ 90{}^\circ $
D) $ 180{}^\circ $ , $ 0{}^\circ $ and $ 90{}^\circ $
Correct Answer: A For 17 N both the vector should be parallel i.e. angle between them should be zero. For 7 N both the vectors should be antiparallel i.e. angle between them should be $ 180{}^\circ $ For 13 N both the vectors should be perpendicular to each other i.e. angle between them should be $ 90{}^\circ $
