Question 1
1 / -0

The foot of ⊥ from (α,β,γ) on y-axis is

A
(α,0,0)

B
(0,β,0)

C
(0,0,γ)

D
(0,0,0)
Question 2
1 / -0

The medians of a triangle are concurrent at the point called

A
orthocentre

B
incentre

C
circumcentre

D
centroid

Solution

The centroid is the point of concurrency of the medians of the triangle.it is a point of centre of gravity of triangle
Question 3
1 / -0

The perpendicular distance of the point (6, 5, 8) from y–axis is

A
10 units

B
6 units

C
8 units

D
9 units
Question 4
1 / -0

The graph of the equation x² + y² = 0 in three dimensional space is

A
X-axis

B
Y-axis

C
Z-axis

D
XY-plane
Question 5
1 / -0

The distance of the point ( 3, 4, 5) from X- axis is

A
3

B
5

C
√34

D
√41

Solution

The distance of the point ( 3, 4, 5) from X- axis is

let L be the foot of perpendicular from the point ( 3, 4, 5) to X axis ,then coordinate of L will be (3,0,0) [ because on X axis y and z coordinate are zero]

then distance of the point ( 3, 4, 5) from X- axis i.e. from L (3,0,0) is given by√ (3−3)2+(4−0)2+(5−0)=√ 41
Question 6
1 / -0

The distance of point (3, 4, 5) from x-axis is

A
3

B
5

C
√34

D
√41

1 / -0

The distance of point A (2, 3, 4) from x-axis is

A
5

B
√13

C
2√5

D
5√2
