A line of fixed length `a+b` moves so that its ends are always on two fixed perpendicular straight lines. Then the locus of the point which divides this line into portions of length `aa n db` is a/an ellipse (b) parabola straight line (d) none of these

A line of fixed length a+b moves so that its ends are always on two fixed perpendicular straight lines. Then the locus of the point which divides this line into portions of length aa n db is (a) an ellipse (b) parabola (c) straight line (d) none of these

A line of fixed length a+b moves so that its ends are always on two fixed perpendicular straight lines. Then the locus of the point which divides this line into portions of length aa n db is (a) an ellipse (b) parabola (c) straight line (d) none of these

A line of fixed length a+b moves so that its ends are always on two fixed perpendicular straight lines. Then the locus of the point which divides this line into portions of length aa n db is a/an (a)ellipse (b) parabola (c)straight line (d) none of these

A line of fixed length a+b moves so that its ends are always on two fixed perpendicular straight lines.Then the locus of the point which divides this line into portions of length a and bis a/an ellipse (b) parabola straight line (d) none of these

A line of fixed length a + b moves so that its ends are always on two fixed perpendicular straight lines. Then the locus of a point which divides this line into portions of length a and b is

A line of length a+b moves in such a way that its ends are always on two fixed perpendicular straight lines. Then the locus of point on this line which devides it into two portions of length a and b ,is :

A line of fixed length (a + b) moves so that its ends are always on two fixed perpendicular straight lines. Prove that a marked point on the line which divides this line into portions of length 'a' and 'b' describes an ellipse and also find the eccentricity of the ellipse when a = 8, b=12 .
