If vector `hati+hatj-hatk" and "2hati+2hatj+lambdahatk` are parallel than find out the value of `lambda` :-

The vectors veca=hati-2hatj+3hatk, vecb=-2hati+3hatj-4hatk and vec c=hati-3hatj+lambdahatk are coplanar if the value of lambda is

The vectors veca=hati-2hatj+3hatk, vecb=-2hati+3hatj-4hatk and vec c=hati-3hatj+lambdahatk are coplanar if the value of lambda is

The scalar product of the vector hati+hatj+hatk with a unit vector along the sum of vectors 2hati+4hatj-5hatk and lambda hati+2hatj+3hatk is equal to one. Find the value of lambda .

The scalar product of the vector hati+hatj+hatk with a unit vector along the sum of vectors 2 hati+4 hatj-5 hatk and lambda hati+2 hatj+3 hatk is equal to one. Find the value of lambda

The scalar product of the vector hati+hatj+hatk with a unit vector along the sum of vectors 2hati+4hatj-5hatk and lambdahati+2hatj+3hatk is equal to one. Find the value of lambda .

If veca=hati+hatj-lambdahatk and vecb=2hati+lambdahatk are per[endicular to each other, the value of lambda is :

If the vectors hati-hatj+hatk,3hati+hatj+2hatk and hati+lambda hatj-3hatk are coplanar then find the value of lambda .
