1.	A plane cuts off intercepts `3,-4,6` on the coordinate axes. The length of perpendicular from the origin to this plane isA. `5/sqrt(29)` unitsB. `8/sqrt(29)` unitsC. `6/sqrt(29)` unitsD. `12/sqrt(29)` units
Answer» Correct Answer - d The given plane is `x/3+y/-4+z/6=1 rArr 4x-3y+2z=12` `therefore p=(\|4 xx 0-3 xx0+2 xx 0-12\|)/sqrt(4^(2)+(-3)^(2)+2^(2))=12/sqrt(29)` units.
