Misc 23 The normal to the curve π₯^2=4π¦ passing (1, 2) is (π΄) π₯ + π¦ = 3 (π΅) π₯ β π¦ = 3 (πΆ) π₯ + π¦ = 1 (π·) π₯ β π¦ = 1Since (1, 2) lies on normal, it will satisfy its equation
Option 1: π+π=π
Putting π₯=1 & π¦=2 in equation
1 +2=3
3=3
This is true
So, it is the equation of Normal
Option 2: πβπ=π
Putting π₯=1 & π¦=2 in equation
1 β2=3
β1=3
This is false
So, it is not equation of Normal
Option 3: π+π=π
Putting π₯=1 & π¦=2 in equation
1 +2=1
3=1
This is false
So, it is not equation of Normal
Option 4: πβπ=π
Putting π₯=1 & π¦=2 in equation
1 β1=1
0=1
This is false
So, it is not equation of Normal
Hence, Correct Answer is (A)
