यदि निम्न समतल परस्पर लंबवत हो, तो `lambda` का मान ज्ञात कीजिए -
`overline(r).(2i - j + lambda k) = 5` और `overline(r).(3i +2j +2k) = 4`

If overline(a)*hat(i)=4, then (overline(a)timeshat(j))*(2hat(j)-3hat(k))=

If i-2j, 3j+k and lambda i + 3j are coplanar then lambda =

If I - 2j, 3j + k and lambda I + 3j are coplanar. Then lambda =

यदि "(3+4i)/(4-5i)=a+ib" हो,तो "*a'" और ' "b" ज्ञात कीजिए। "

The vectors lambda i + j +2k, i + lambda j - k, 2i-j+ lambda k are coplanar if

The distance between the line vec r = 2i+2j+3k + lambda (i-j+4k) and the plane vec r . (i+5j+k) = 5 is

If angle bisector of overline(a) = 2hat(i) + 3 hat(j) + 4 hat(k) and overline(b) = 4hat(i) - 2 hat(j) + 3 hat(k) is overline(c ) = alpha hat(i) + 2 hat(j) + beta hat(k) then
