If the unit vectors vec(e_(1)) and vec(e_(2)) are inclined at an angle 2theta and |vec(e_(1)) - vec(e_(2))| lt 2 , then for theta in [0,pi], theta may lie in the interval

If \ vec a\ a n d\ vec b are two unit vectors inclined at an angle theta such that |a+b|,1, then theta (2pi)/3 c. pi/3

If vec a and vec b are unit vectors making an angle a with each other,such that alpha in(0,pi) and |vec a+2vec b|<5 , then alpha lies in the interval

If |vec a+vec b|<|vec a-vec b|, then the angle between vec a and vec b can lie in the interval a.(pi/2,pi/2) b.(0,pi) c.(pi/2,3 pi/2) d.(0,2 pi)

Let vec a and vec b are two perpendicular unit vectors.If vec c is another unit vector equally inclined at angle theta to the vectors vec a and vec b , then the set of exhaustive values of theta in [0,2 pi] is (A) (0,(pi)/(2))(B)[0,(pi)/(4))(C)((pi)/(2),(3 pi)/(4))(D)[(pi)/(4),(3 pi)/(4)]

If theta is the angle between two vectors vec a\ a n d\ vec b ,\ t h e n\ vec adot vec bgeq0 only when 0

If vec a,vec b and vec c are non-coplanar unit vectors such that vec a xx(vec b xxvec c)=(vec b+vec c)/(sqrt(2)), then the angle between vec a and vec b is a.3 pi/4b. pi/4 c.pi/2d. pi

If the vectors vec a and vec b are linearly idependent satisfying (sqrt(3)tan theta+1)vec a+(sqrt(3)sec theta-2)vec b=0 then the most general values of theta are a.n pi-(pi)/(6),n in Z b.2n pi+-(11 pi)/(6),n in Z c.n pi+-(pi)/(6),n in Z d.2n pi+(11 pi)/(6),n in Z
