`bar(a)` and `bar(b)` are non-collinear vectors. If `bar(c)=(x-2)bar(a)+bar(b)` and `bar(d)=(2x+1)bar(a)-bar(b)` are collinear, then find the value of x.

bar a and bar b are non- collinear vectors. If barc = (x-2)bar a+bar b and bar d = (2x+1)bar a- bar b are collinear , then find the value of x

If the vectors bar(a)=-2bar(i)+3bar(j)+ybar(k) and bar(b)=xbar(i)-6bar(j)+2bar(k) are collinear, then the value of x+y is

If the vectors bar(a)=-2bar(i)+3bar(j)+ybar(k) and bar(b)=xbar(i)-6bar(j)+2bar(k) are collinear,then the value of x+y is

The vectors bar(a) and bar(b) are non-collinear.If bar(a)+(x+1)bar(b) and (2x-3)bar(b)-bar(a) are collinear,then the value of x is

If bar(a), bar(b) are two non collinear vectors, then bar(r)=sbar(a)+tbar(b) represents

If bar(a), bar(b) are two non-collinear vectors such that bar(a)+2bar(b) and bar(b)-lambdabar(a) are collinear, find lambda .

If bar(a) and bar(b) are two non-zero, non-collinear vectors such that xbar(a)+ybar(b)=bar(0) then

Let bar(a) and bar(b) be unit vector.If the vectors bar(c)=bar(a)+2bar(b) and bar(d)=5bar(a)-4bar(b) are perpendicular to the each other then angle between bar(a) and bar(b) is
