Question

Centre of arc of Circle is (10,10,0)
Origin is shifted to the point (2,0,0)
along with coordinate axis and then
Rotation carried out about Xaxis
through an angle 60°. The New
coordinates of the Centre in neus
coordinale system are..​

Answer 1

Answer:

Correct option is

D

1

Let X and Y be the coordinates in the new coordinate system. 

When  axis  are  rotated  through  60∘, co-ordinates are changed to 

x=X(21)−Y(23)

y=X(23)+Y(21)

3x+4y=5 

In the new coordinate system, the line will be represented as  

3(X(21)−Y(23))+4(X(23)+Y(21))=5

X(3+43)+Y(4−33)=10

⇒a=3+4310;b=4−3
