Last updated at May 29, 2023 by Teachoo
A cricket match is organized between two Clubs A and B for which a team from each club is chosen. Remaining players of Club A and Club B are respectively sitting on the plane represented by the equation r. (2i β j + k) = 3 and r . (i + 3j + 2k) = 8, to cheer the team of their own clubs.
Based on the above answer the following:
Question 1
The Cartesian equation of the plane on which players of Club A are seated is
(a) 2π₯ β π¦ + π§ = 3
(b) 2π₯ β π¦ + 2π§ = 3
(c) 2π₯ β π¦ + π§ = β3
(d) π₯ β π¦ + π§ = 3
Question 2
The magnitude of the normal to the plane on which players of club B are seated, is
(a) β15
(b) β14
(c) β17
(d) β20
Question 3
The intercept form of the equation of the plane on which players of Club B are seated is
(a) x/8+y/(8/3)+z/2=1
(b) x/5+y/(8/3)+z/3=1
(c) x/8+y/(8/3)+z/4=1
(d) x/8+y/7+z/2=1
Question 4
Which of the following is a player of Club B?
(a) Player sitting at (1, 2, 1)
(b) Player sitting at (0, 1, 2)
(c) Player sitting at (1, 4, 1)
(d) Player sitting at (1, 1, 2)
Question 5
The distance of the plane, on which players of Club B are seated, from the origin is
(a) 8/β14 units
(b) 6/β14 units
(c) 7/β14 units
(d) 9/β14 units

Question A cricket match is organized between two Clubs A and B for which a team from each club is chosen. Remaining players of Club A and Club B are respectively sitting on the plane represented by the equation π β. (2π β β π β + π β) = 3 and π β. (π β + 3π β + 2π β) = 8, to cheer the team of their own clubs. Based on the above answer the following:Question 1 The Cartesian equation of the plane on which players of Club A are seated is (a) 2π₯ β π¦ + π§ = 3 (b) 2π₯ β π¦ + 2π§ = 3 (c) 2π₯ β π¦ + π§ = β3 (d) π₯ β π¦ + π§ = 3(a) 2π₯ β π¦ + π§ = 3
