Let E1 and E2 be two ellipses whose centers are at origin. The major axes of E1 and E2 lie along the x−axis and y−axis, respectively. Let S be the circle x2+(y−1)2=2. The straight line x+y=3 touches the curves S,E1 and E2 at P,Q and R, respectively. Suppose that PQ=PR=2√23. If e1 and e2 are the eccentricities of E1 and E2, respectively then the correct expression(s) is (are)
Nice explanation sir ,but radius is √2 and it is not used in the solution. Thank you sir
Haa yes , radius is √2. Thank you
Super sir
Solution is nice
