The projection of the line segment joining the points ( -1,0,3) and (2,5,1) on the line whose direction ratios are 6,2,3 is `alpha` then find the value of `7 alpha`

Text Solution

Verified by Experts

The correct Answer is:
22
Projection=`[12-(-1)](6)/(7)+[5-0](2)/(7)+[1-3](3)/(7)" "=(18+10-6)/(7)=(22)/(7)=alpha`
`therefore" "7alpha=22`
