If `veca, vecb,vecc` are unit vectors such that `veca` is perpendicular to the plane of `vecb, vecc` and the angle between `vecb,vecc` is `pi/3`, then `|veca+vecb+vecc|=`

If veca,vecb,vecc are unit vectors such that veca is perpendicular to the plane vecb and vecc and angle between vecb and vecc is (pi)/(3) , than value of |veca+vecb+vecc| is

If veca,vecb,vecc are unit vectors such that veca is perpendicular to vecb and vecc and |veca+vecb+vecc|=1 then the angle between vecb and vecc is (A) pi/2 (B) pi (C) 0 (D) (2pi)/3

If veca,vecb,vecc are unit vectors such that veca is perpendicular to vecb and vecc and |veca+vecb+vecc|=1 then the angle between vecb and vecc is (A) pi/2 (B) pi (C) 0 (D) (2pi)/3

If veca, vecb, vecc are unit vectors such that veca. vecb =0 = veca.vecc and the angle between vecb and vecc is pi/3 , then find the value of |veca xx vecb -veca xx vecc|

If veca, vecb, vecc are unit vectors such that veca. Vecb =0 = veca.vecc and the angle between vecb and vecc is pi/3 , then find the value of |veca xx vecb -veca xx vecc|

If veca, vecb, vecc are vectors such that veca.vecb=0 and veca + vecb = vecc then:

If veca, vecb, vecc are vectors such that veca.vecb=0 and veca + vecb = vecc then:
