## Q1. If the foot of the perpendicular from the origin to a plane is (a, b, c), then equation of the plane is  x/a+y/b+z/c=1  ax+by+cz=1  ax+by+cz=0  ax+by+cz=a^2+b^2+c^2 Solution Let P be the foot of the perpendicular from the origin on the plane, then direction ratios ofOP, the normal to the plane area-0,b-0,c-0 ie,a,b,c. Also, since, it passes through (a,b,c), the equation of the plane is a(x-a)+b(y-b)+c(z-c)=0 ⇒ ax+by+cz=a^2+b^2+c^2 Q2. The point on the line x-21=y+3-2=z+5-2 at a distance of 6 from the point (2, -3, -5) is  (3, -5,-3)  (4, -7, -9)  (0, 2, -1)  (-3, 5, 3) Solution DC’s of the given line are 1/3,-2/3,-2/3 Hence, the equation of line can be point in the form (x-2)/(1/3)=(y+3)/(-2/3)=(z+5)/(-2/3)=r ∴ Point is (2+r/3,-3-2r/3,-5-2r/3) ∴r=±6 Q3.  The distance of the point P(1,2,3) from the line which passes through the point A4,2,2and parallel to the vector 2i+3j+6k is   1  √7  √5  √10 Solution Q4.  Equation of plane passing through the points (2, 2, 1), (9, 3, 6) and perpendicular to the plane 2x+6y+6z-1=0, is  3x+4y+5z=9  3x+4y-5z+9=0  None of these  3x+4y-5z-9=0 Solution Equation of a plane passing through (2, 2, 1) is a(x-2)+b(y-2)+c(z-1)=0 … (i) This passes through (9, 3, 6) and is perpendicular to 2x+6y+6z-1=0 ∴7a+b+5c=0 and, 2a+6b+6c=0 Solving these two by cross-multiplication, we get a/(-24)=b/(-32)=c/40⇒a/(-3)=b/(-4)=c/5 Substituting the values of a,b,c in (i), we get 3x+4y-5z-9=0 as the required plane Q5.The vector equation of the plane through the point 2, 1, -1 and passing through the line of intersection of the plane ri+3 j-k=0 and rj+2 k=0, is  r.(i+9 j+11 k)=0  r.(i+9 j+11 k)=6  r.(i-3j-13k)=0  None of these Solution  The vector equation of a plane through the line of intersection of the planes r ⃗∙(i ̂+3j ̂-k ̂ )=0 and r ⃗∙(j ̂+2k ̂ )=0 can be written as {r ⃗∙(i ̂+3j ̂+-k ̂ )}+λ{r ⃗∙(j ̂+2k ̂ )}=0 …(i) This passes through 2i ̂+j ̂-k ̂ ∴(2i ̂+j ̂-k ̂ )∙(i ̂+3j ̂-k ̂ )+λ(2i ̂+j ̂-k ̂ )∙(j ̂+2k ̂ )=0 ⇒(2+3+1)+λ(0+1-2)=0⇒λ=6 Putting the value of λ in (i), we get the equation of the required plane as r ⃗∙(i ̂+9j ̂+11k ̂ )=0 Q6. The equation of the plane passing through the points (0, 1, 2) and (-1, 0, 3) and perpendicular to the plane 2x+3y+z=5 is  3x-4y+18z+32=0  4x-3y+z+1=0 4x+3y-17z+31=0  3x+4y-18z+32=0 Solution Any plane passing through (0, 1, 2) is a(x-0)+b(y-1)+c(z-2)=0 ⟹ax+b(y-1)+c(z-2)=0 ….(i) Since, it is passing through (-1,0,3), we get -a-b+c=0 …..(ii) Also, Eq. is perpendicular to 2x+3y+z=5 ∴2a+3b+c=0 ….(iii) On solving Eqs. (ii) and (iii), we get a/(-4)=b/3=c/(-1) ∴From Eq. (i) -4x+3(y-1)-1(z-2)=0 ⟹4x-3y+z+1=0 Q7.The centre of sphere passes through four points (0, 0, 0), (0,2,0), (1,0, 0)and (0, 0, 4) is  (-1/2,1,2)  (1,1/2,2)  (1/2,1,2)  (1/2,1,-2) Solution Let the equation of sphere passing through (0, 0, 0) be x^2+y^2+z^2+2ux+2vy+2wz=0 Also, it passes through (0, 2, 0), (1, 0, 0), (0, 0, 4) respectively are 4+4v=0 ⟹v=-1 1+2u=0⟹u=-1/2 and 16+8w⟹w=-2 ∴ Centre is (-u,-v,-w)=(1/2,1,2) Q8.A plane π makes intercepts 3 and 4 respectively on z-axis and x-axis. If π is parallel to y-axis, then its equation is  3z+4x=12  3x+4z=12  3y+4z=12  3z+4y=12 Solution Given, a=4,c=3 Equation of the plane π is x/4+y/b+z/3=1 Since, π is parallel to y-axis ∴Coefficient of y=0 ie,1/b=0 Thus, the equation of plane π is x/4+z/3=1 ⟹3x+4z-12=0 Q9.The length of the perpendicular from the origin to the plane passing through three non-collinear points a, b, c is  None of these  2[a ⃗ b ⃗ c ⃗ ]/|a ⃗×b ⃗+b ⃗×c ⃗+c ⃗×a ⃗ |  [a ⃗ b ⃗ c ⃗ ]  [a ⃗ b ⃗ c ⃗ ]/|a ⃗×b ⃗+c ⃗×a ⃗+b ⃗×c ⃗ | Solution The vector equation of the plane passing through points a ⃗,b ⃗,c ⃗ is r ⃗∙(a ⃗×b ⃗+b ⃗×c ⃗+c ⃗×a ⃗ )=[a ⃗ b ⃗ c ⃗ ] Therefore, the length of the perpendicular from the origin to this plane is given by Q10. If P3, 2, -4, Q(5, 4, -6) and R(9, 8, -10) are collinear, then R divides PQ in the ratio  3∶2 internally  3 :2 externally  2∶1 internally 2∶1 externally Solution Suppose R divides PQ in the ratio λ∶1. Then, the coordinates of R are ((5 λ+3)/(λ+1),(4 λ+2)/(λ+1),(-6 λ-4)/(λ+1)) But, the coordinates of R are given as (9,8,-10) ∴(5 λ+3)/(λ+1)=9,(4 λ+2)/(λ+1)=8 and (-6 λ-4)/(λ+1)=-10 ⇒λ=-3/2 Hence, R divides PQ externally in the ratio 3 : 2 var answers = ["D","B","D","D","A","B","C","B","D","B"];
