If the lines `(x-1)/(-3)=(y-2)/(2k)=(z-3)/2` and `(x-1)/(3k)=(y-1)/1=(z-6)/(-5)` are perpendicular, find the value of k.

If the lines (x-1)/(-3)=(y-2)/(2k)=(z-3)/2 and (x-1)/(3k)=(y-1)/1=(z-6)/(-3) are perpendicular, find the value of k.

If the lines (x-1)/(-3)=(y-2)/(2k)=(z-3)/(2)(x-1)/(3k)=(y-1)/(1)=(z-6)/(-5) are perpendicular,find the value of k.

If the lines (x-1)/-3 = (y-2)/(2k) = (z-3)/2 and (x-1)/(3k) = (y-1)/1 = (z-6)/-5 are perpendicular, then find the value of k.

If the lines: (x-1)/(3k)=(y-2)/(2)=(z+3)/1 and (x-1)/(2)=(y-1)/(k)=(z-6)/-5 are perpendicular, find the values of k.

If the lines (x-1)/(-3)=(y-2)/(-2y)=(z-3)/(2) and (x-1)/(k)=(y-2)/(1)-(z-3)/(5) are perpendicular,find the value of k and hence find the equation of plane containing these lines.

If the lines (x-1)/(-3)=(y-2)/(-2k)=(z-3)/2 and (x-1)/k=(y-2)/1=(z-3)/5 are perpendicular, find the value of k and hence find the equation of plane containing these lines.

If the lines: (x-1)/-3=(y-2)/(-2k)=(z-3)/2 and (x-1)/k=(y-2)/1=(z-3)/5 are perpendicular, find the values of k and hence find the equation of plane containing these lines.

If the lines (x-1)/(-3)=(y-2)/(2k)=(z-3)/(-2) and (x-1)/(3k)=(y-5)/1=(z-6)/(-5) are at right angle, then find the value of k .
