उत्तर
The vector equation of the plane passing through A`(bara)` and perpendicular to `bar"n" "is" bar"r".bar"n" = bar"a".bar"n"`.
M(1,0,0) is the foot of the perpendicular drawn from origin to the plane. Then the plane is passing through M and is perpendicular to OM.
If `bar"m"` is the position vector of M, then `bar"m" = hat"i"`.
Normal to the plane is
`bar"n" = bar"OM" = hat"i"`
`bar"m".bar"n" = hat"i".hat"i"` = 1
∴ the vector equation of the required plane is
`bar"r".hat"i"` = 1.
