If `a + bne 0` , find the coordinates of focus and the length of latus rectum of the parabola `y^(2) = 2 mx ` which passes through the point of intersection of the straight lines `(x)/(a)+(y)/(b)=1` and `(x)/(b)+(y)/(a)=1` .

Text Solution

Verified by Experts

The correct Answer is:
2m `=2* (ab)/(4(a+b))=(ab)/(a+b)` unit .
