If bar(a), bar(b), bar(c) are noncoplana...

If `bar(a), bar(b), bar(c)` are noncoplanar, find the point of intersection of the line passing through the points `2bar(a)+3bar(b)-bar(c), 3bar(a)+4bar(b)-2bar(c)` with the line joining the points `bar(a)-2bar(b)+3bar(c) and bar(a)-6bar(b)+6bar(c)`.

Text Solution

Verified by Experts

The correct Answer is:
they have only one point of intersection namely ` bar(a) + 2 bar(b)`
