`lambda` का मान ज्ञात कीजिए यदि निम्न सदिश सम- तलीय हैं:
`hati-hatj+hatk, 2hati+hatj-hatk, lambda hati-hatj+lambda hatk`.

veca=hati-hatj+hatk, vecb=2hati+hatj-hatk, vec c=lambda hati-hatj+lambda hatk are coplanar then lambda is :

If hati-2hatj,3hatj+4hatk and lambda hati+3hatj are coplanar, then lambda is equal to

Find lambda if the vectors hati-hatj+hatk, 3hati-hatj+2hatk and hati+lambda hatj-3hatk are coplannar.

The value of lambda, for which the four points 2hati+3hatj-hatk, hati-2hatj+3hatk, 3hati+4hatj-2hatk, hati-6hatj+lambda hatk are coplanar, is

Find lambda if the vectors hati+hatj+2hatk, lambdahati-hatj+hatk and 3hati-2hatj-hatk are coplanar.

Find the angle between the following pairs of lines : (i) vec(r) = 2 hati - 5 hatj + hatk + lambda (3 hati + 2 hatj + 6 hatk ) and vec(r) = 7 hati - 6 hatk + mu (hati + 2 hatj + 2 hatk) (ii) vec(r) = 3 hati + hatj - 2 hatk + lambda (hati - hatj - 2 hatk ) and vec(r) = 2 hati - hatj - 56 hatk + mu (3 hati - 5 hatj - 4 hatk) .

The value of ‘ lambda ’ so that the vectors hati - 3̂ hatj + hatk , 2̂ hati + lambda hatj + hatk and 3 hati + hatj - 2 hatk are coplanar, will be
