He notes that he can read the messages of value system ‘Honesty’ and ‘Respect for other’ on the poles which ever side he moves, then answer the following questions which are based on above it.

Question. The path traced by the man will be
(a) an ellipse
(b) a parabola
(c) a hyperbola
(d) a circle

A

Question. Value of a for the standard equation of path is
(a) 10
(b) 5
(c) 15
(d) 20

B

Question. Value of b for the standard equation of path is
(a) 3
(b) 4
(c) 5
(d) 6

A

Question. Equation of path is

C

Question. Value of (2 a + b) is
(a) 10
(b) 13
(c) 15
(d) 18

B

Due to heavy storm, an electric wire got bent as shown in figure. It followed a mathematical shape. Answer the following question below.

Question. Name the shape in which the wire is bent
(a) circle
(b) parabola
(c) ellipse
(d) hyperbola

C

Question. The equation of the shape of curve is

A

Question. The eccentricity of the given shape is
(a) 2/3
(b) √x/√3
(c) √5/3
(d) √5/4

C

Question. The length of the latusrectum of the shape is
(a) 9 units
(b) 8/3 units
(c) 4/3 units
(d) None of the above

B

Question. Foci of the shape is
(a) (± 3, 0)
(b) (± √5, 0)
(c) (0, ± 2)
(d) (0, ± √5)

B

Assertion & Reasoning Based Questions :

(a) Assertion and Reason both are correct statements and Reason is the correct explanation of Assertion.
(b) Assertion and Reason both are correct statements but Reason is not the correct explanation of Assertion.
(c) Assertion is correct statement but Reason is wrong statement.
(d) Assertion is wrong statement but Reason is correct statement.

Question. Assertion : Eccentricity is always less than 1.
Reason : Foci are at a distance of ae from the centre.

D

Question. Assertion : A line through the focus and perpendicular to the directrix is called the x-axis of the parabola.
Reason : The point of intersection of parabola with the axis is called the vertex of the parabola.

D

Question. Assertion : The length of major and minor axes of the ellipse 5x2 + 9y2 – 54y + 36 = 0 are 6 and 10, respectively.
Reason : The equation 5x2 + 9y2 – 54y + 36 = 0 can be expressed as 5x2 + 9(y – 3)2 = 45.

D

Question. Assertion : If the equation of standard parabola has a term y2, then the axis of symmetry is along the x-axis.
Reason : If the equation of standard parabola has a term x2, then the axis of symmetry is along the x-axis.
