दोनों सदिशों `bara + barb` और `bara - barb` के लंबवत ek मात्रक सदिश ज्ञात कीजिए, जहाँ `bara = hati + hatj + hatk` और `barb = hati + 2hatj + 3hatk`

If bara=hati+hatj+hatk , bara.barb=2 and bara times barb=2hati+hatj-3hatk then

If bara=hati+hatj+hatk , bara.barb=2 and bara times barb=2hati+hatj-3hatk then

If the vectors bara = hati + hatj + hatk, barb = hati - hatj +2hatk and barc = xhati + (x-2)hatj - hatk are coplanar, then x =

If bara =3 hati - 2hatj +7 hatk, barb = 5hati + hat j -2 hatk and barc = hati + hatj - hat k, " then find "bara * (barb xx barc) .

IF bar a = hati + hatj +2 hatk , bar b = 2 hati - hatj +hatk and bar c = 3 hati - hatk and bar c = m bara + n barb then m+ n =

Select and write the appropriate answer from the given alternatives in each of the following sub- questions: if hata = 3hati - hatj + 4hatk, barb = 2hati + 3hatj - hatk, barc = - 5 hat i + 2hatj + 3hatk then bara . (barb xx barc) = ……….

Find the area of a parallelogram whose diagonals are determined by the vectors bara=3 hati +hatj -2 hatk and barb=hati-3hatj+4hatk

If bara=hati+hatj+hatk, bara.barb=2 and bara times barb=2hati+hatj-3hatk then barb is equal to

If bara = 2hati + 3hatj - hatk, barb = hati + 2hatj - 5hatj, barc = 3hati + 5hatj - hatk , then a vector perpendicular to bara and lies in the plane containing barb and barc is………….
