The line of greatest slope on an inclined plane `P_1` is the line in the plane `P_1` which is perpendicular to the line of intersection of the plane `P_1` and a horizontal plane`P_2`.
Q. The coordinate of a point on the plane `2x+y-5z=0, 2sqrt(11)` unit away from the line of intersection of `2x+y-5z=0 and 4x-3y+7z=0` are

Options

A. `(x)/(3)=(y)/(1)=(z)/(-1)`
B. `(x)/(3)=(y)/(-1)=(z)/(1)`
C. `(x)/(-3)=(y)/(1)=(z)/(1)`
D. `(x)/(1)=(y)/(3)=(z)/(-1)`

Answer

(b)
