1.	If three vectors `xa-2b+3c, -2a+yb-4c` and `-zb+3c` are coplanar, where `a,b` and `c` are unit (or any) vectors thenA. `xy+3zx-3z=4`B. `2xy-3zx-3z-4=0`C. `4xy-3zx-3z=4`D. `xy-2zx-3z-4=0`
Answer» (d) Condition of coplanarity, `\|(x,-2,3),(-2,y,-4),(0,-z,3)\|=0` `impliesx(2-4z)+2(-4-0)+3(2z-0)=0` `implies2xy-4zx-8+6z=0` ltbrrgt `impliesxy-2zx-4+3z=0`
