Previous Year Questions (2022-2024)
Year 2022
- Find equation of line through (1,2,3) with DR 2,3,4.
Show Solution
(x-1)/2 = (y-2)/3 = (z-3)/4 - Find distance from (1,2,3) to plane 2x+3y-z+5=0.
Show Solution
d = |2(1)+3(2)-1(3)+5|/√4+9+1\n= |2+6-3+5|/√14 = 10/√14 units
Year 2023
- Find equation of line through (1,2,3) with DR 2,3,4.
Show Solution
(x-1)/2 = (y-2)/3 = (z-3)/4 - Find distance from (1,2,3) to plane 2x+3y-z+5=0.
Show Solution
d = |2(1)+3(2)-1(3)+5|/√4+9+1\n= |2+6-3+5|/√14 = 10/√14 units
