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

Projection `[ 12- ( - 10 )] ( 6)/( 7 ) + [ 5- 0 ] ( 2)/( 7) + [1-3] (3)/( 7) = ( 18+ 10 -6)/( 7) = ( 22)/( 7 ) = alpha`
`:. 7 alpha = 22`
