From the point `P(a ,b ,c),`let perpendicualars `P La n dP M`be drawn to `Y O Za n dZ O X`planes,respectively. Then the equation of the plane `O L M`isa. `x/a+y/b+z/c=0`b. `x/a+y/b-z/c=0`c. `x/a-y/b-z/c=0`d. `x/a-y/b+z/c=0`A. `(x)/(a)+(y)/(b)+(z)/(c)=0`B. `(x)/(a)+(y)/(b)-(z)/(c)=0`C. `(x)/(a)-(y)/(b)-(z)/(c)=0`D. `(x)/(a)-(y)/(b)+(z)/(c)=0` |

Answer» Correct Answer - b Coordinates of L and M are (0,b,c) and (a,0,c), respectively. Therefore, the equation of the plane passing through (0,0,0), (0,b,c) and (a,0,c) is `|[x-0,y-0,z-0],[0,b,c],[a,0,c]|=0or(x)/(a)+(y)/(b)-(z)/(c)=0` |
