The projection of the line segment joining the points (1, –1, 3) and (2, –4, 11) on the line joining the points (–1, 2, 3) and (3, –2, 10) is ____________.

Step-by-Step Verified Solution

Let A (1, – 1, 3), B(2, – 4, 11), C (–1, 2, 3) & D (3, –2, 10)

∴ AB→=i^−3j^+8k^

⇒ CD→=4i^−4j^+7k^

Projection of AB→ on CD→ = AB→.CD→|CD→|

= 4+12+5616+16+49

= 729

= 8
