" If "vec rvec a" and "vec b" be two vectors of equal magnitude,then "(vec a+vec b)*(vec a-vec b)

If vec a and vec b are vectors of equal magnitude, write the value of (vec a+vec b)vec a-vec b

If vec a\ a n d\ vec b are vectors of equal magnitude, write the value of ( vec a+ vec b)dot( vec a- vec b)dot

If vec a and vec b are vectors, each of magnitude 3 then |vec a+ vec b|^2 + |vec a - vec b|^2= __________.

If vec a and vec b are two orthogonal vectors of equal magnitude such that |3vec a+4vec b|+|4vec a-3vec b|=20 then |(vec a xxvec b)xxvec a|

If vec a and vec b are two non -zero vectors, then (vec a + vec b) .(vec a - vec b) is equal to

If vec a, vec b, vec c are any three mutually perpendicular vectors of equal magnitude a, then |vec a+ vec b+ vec c| is equal to
