Misc 22 The normal at the point (1,1) on the curve 2𝑦+π‘₯^2=3 is (𝐴) π‘₯ + 𝑦 = 0 (𝐡) π‘₯ – 𝑦 = 0 (𝐢) π‘₯ + 𝑦 +1 = 0 (𝐷) π‘₯ – 𝑦 = 1Since (1, 1) lies on normal, it will satisfy its equation Option 1: 𝒙+π’š=𝟎 Putting π‘₯=1 & 𝑦=1 in equation 1 +1=0 2=0 This is false So, it is not equation of Normal Since (1, 1) lies on normal, it will satisfy its equation Option 1: 𝒙+π’š=𝟎 Putting π‘₯=1 & 𝑦=1 in equation 1 +1=0 2=0 This is false So, it is not equation of Normal Option 4: π’™βˆ’π’š=𝟏 Putting π‘₯=1 & 𝑦=1 in equation 1 βˆ’1=1 0=1 This is false So, it is not equation of Normal Hence, Correct Answer is (B)
