The curves `y=a e^x` and `y=b e^(-x)` cut orthogonally, if `a=b` (b) `a=-b` (c) `a b=1` (d) `a b=2`

The curves y=a e^x and y=b e^(-x) cut orthogonally, if (a) a=b (b) a=-b (c) a b=1 (d) a b=2

If the curves y=2\ e^x and y=a e^(-x) intersect orthogonally, then a= 1//2 (b) -1//2 (c) 2 (d) 2e^2

If the curves y=2\ e^x and y=a e^(-x) intersect orthogonally, then a= (a)1//2 (b) -1//2 (c) 2 (d) 2e^2

The curves x^2/a+y^2/b=1 and x^2/a_1+y^2/b_1=1 will cut orthogonally if (a-b) =
