| Find the value of γ for which the line  is parallel to the plane

A. -4/13

B. 13/4

C. -7/4

D. None of the above

Right Answer is: C

SOLUTION

Clearly, the given line must be perpendicular to the given plane

Direction ratio of the given line is 2,1, γ

Direction ratio of the normal to the given plane are 2, 3, 4

∴ (2×2)+(3×1)+(γ×4)=0

4γ=-7

γ=-7/4
