`alpha and beta` are unit vectors inclined to each other at an angle `alpha,alpha in (0, pi) and |veca + vecb| < 1`, Then `alpha in`

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

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

If veca, vecb and vecc are three units vectors equally inclined to each other at an angle alpha . Then the angle between veca and plane of vecb and vecc is

If veca, vecb and vecc are three units vectors equally inclined to each other at an angle alpha . Then the angle between veca and plane of vecb and vecc is

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
