Solution
The correct option is
D
(

,
0
)
We know that if a point
P
(
x
,
y
)
divides the line segment
A
B
joining the points
A
(
x
1
,
y
1
)
&
B
(
x
2
,
y
2
)
in the ratio
m
:
n
then, by the section formula, we have
x
=
n
x
1
+
m
x
2
m
+
n
&
y
=
n
y
1
+
m
y
2
m
+
n
.
Hence,
m
=
1
,
n
=
2
,
A
=
(
1
,
0
)
and
B
=
(
0
,
0
)
Let
P
(
x
,
y
)
be the required point.
∴
x
=
(
1
×
0
)
+
(
2
×
1
)
1
+
2
=
0
+
2
3
=

3
and
y
=
(
1
×
0
)
+
(
2
×
0
)
1
+
2
=
0
+

3
=

Therefore, the coordinates of the point is
(
2
3
,
0
)
.
