Misc 22 The normal at the point (1,1) on the curve 2๐‘ฆ+๐‘ฅ^2=3 is (๐ด) ๐‘ฅ + ๐‘ฆ = 0 (๐ต) ๐‘ฅ โ€“ ๐‘ฆ = 0 (๐ถ) ๐‘ฅ + ๐‘ฆ +1 = 0 (๐ท) ๐‘ฅ โ€“ ๐‘ฆ = 1Since (1, 1) lies on normal, it will satisfy its equation Option 1: ๐’™+๐’š=๐ŸŽ Putting ๐‘ฅ=1 & ๐‘ฆ=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: ๐’™+๐’š=๐ŸŽ Putting ๐‘ฅ=1 & ๐‘ฆ=1 in equation 1 +1=0 2=0 This is false So, it is not equation of Normal Option 4: ๐’™โˆ’๐’š=๐Ÿ Putting ๐‘ฅ=1 & ๐‘ฆ=1 in equation 1 โˆ’1=1 0=1 This is false So, it is not equation of Normal Hence, Correct Answer is (B)
