If a circle with centre (0, 0) touches the line
5
x
+
12
y
=
1
5x + 12y = 1
5
x
+
12
y
=
1
then its equation will be- (1)
13
(
x
2
+
y
2
)
=
1
13(x^2 + y^2) = 1
13
(
x
2
+
y
2
)
=
1
(2)
x
2
+
y
2
=
169
x^2 + y^2 = 169
x
2
+
y
2
=
169
(3)
169
(
x
2
+
y
2
)
=
1
169(x^2 + y^2) = 1
169
(
x
2
+
y
2
)
=
1
(4)
x
2
+
y
2
=
13
x^2 + y^2 = 13
x
2
+
y
2
=
13
