Let E be an ellipse whose axes are parallel to the co-ordinates axes, having its center at (3,−4), one focus at (4,−4) and one vertex at (5,−4). If mx − y = 4, m > 0 is a tangent to the ellipse E, then the value of 5 m 2 is equal to
Text Solution
Verified by ExpertsThe correct answer is:
3
(3)
Given C(3,−4), S(4,−4)
and A(5,−4)
Hence, a = 2&ae = 1
So, 
Intersecting with given tangent.
Now, D = 0 (as it is tangent)
So, 5 m 2 = 3
