Q. Line x/6 +y/8 =1 intersects the x and y axes at M and N respectively. If the coordinates of the point P lying inside the triangle OMN (where 'O' is origin) are (a, b) such that the areas of the triangle POM, PON and PMN are equal. Find
(a) the-coordinates of the point P and
(b) the radius of the circle escribed opposite to the angle N.
