If P,Q are (2, 5, -7),(-3, 2, 1) respectively, then what are the direction ratios of the line PQ ?

`lt 10, 6, -16 gt`

lt 5, 3, 8 gt

lt -5, -3 -8 gt

None of these

Text Solution

Verified by Experts

The correct Answer is:

Since, coordinates of point P and Q are (2,5,-7) and (-3,2,1) respetively.
Direction ratio of PQ are
`larr3-2,2-5,1+7gti.e.,larr5,-3,8gt`.
