A) \[-3x+2y+6z-7=0\]
B) \[-3x+2y+6z-49=0\]
C) \[3x-2y+6z+7=0\]
D) \[-3x+2y-6z-49=0\]
Correct Answer: B
Solution :
Equation of a plane, when direction ratio and length of perpendicular is given, \[ax+by+cz=p\,\,\sqrt{{{a}^{2}}+{{b}^{2}}+{{c}^{2}}}\] Given, \[(a,\,\,b,\,\,c)\,\,\to \,\,(-\,3,\,\,2,\,\,6)\] \[-\,3x+2y+6z=7\,\sqrt{{{(-\,3)}^{2}}+{{2}^{2}}+{{6}^{2}}}\] \[-\,3x+2y+6z=49\].You need to login to perform this action.
