Show that `oversetrarra = frac(oversetrarri - oversetrarrj)(sqrt2)` is a unit vector.

Chose the correct option If oversetrarra , oversetrarrb , and oversetrarrC are 3 vectors, then which of the following is not correct?

Chose the correct option The angle between oversetrarra and the resultant of (2oversetrarra + oversetrarrb) and (2oversetrarra - oversetrarrb) is

Determine oversetrarra xx oversetrarrb , given oversetrarra = 2hati + 3hatj and oversetrarrb =3hati + 5hatj .

State True/False: If oversetrarra and oversetrarrb are 2 vectors of same magnitude than (oversetrarra + oversetrarrb) is (a) at an angle 45^@ with both vectors.

Show that oversetrarra = 2hati + 5hatj-6hatk and oversetrarrb =hati + frac(5)(2)hatj -3hatk are parallel.

State True/False: If oversetrarra and oversetrarrb are 3 vectors of same magnitude than (oversetrarra + oversetrarrb) is (b) at an angle of 45^@ with any vector

State True/False: If oversetrarra and oversetrarrb are 4 vectors of same magnitude than (oversetrarra + oversetrarrb) is c. in a plain containing the 2 vectors

Find oversetrarrA xx oversetrarrB , where oversetrarrA = 2hati- 5hatj+ 3hatk and oversetrarrB= 3hati+ 4hatj- 9hatk

Show that vectors oversetrarra =2hati + 3hatj + 6hatk , oversetrarrb = 3hati -6hatj + 2hatk and oversetrarrc = 6hati + 2hatj - 3hatk are mutually perpenducalar.

Show that the vectors oversetrarrA = 4hati + 2hatj- 4hatk and oversetrarrB = hati + 4hatj + 3hatK are perpenducular to each other.
