2nd practice problem
Draw locus of point P which moves in such a way that ratio[ its distance from a fixed straight line / its distance from a fixed point] is always constant & equal to 5/3. The fixed point is 50mm away from the fixed straight line. Name the curve.
Hint-
In this problem eccentricity e = 3/5
[ In this problem e = 5/3 so divide CF1 into 8 equal parts & VF1/VC =3/5
