The plane 
is rotated an angle 
about its line of intersection with the plane 
, then the equation to the plane in its new position is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Equation of any plane through the line of intersection of plane 
and 
is 
. Given that angle between plane is 
so, angle between their normals is 
, also direction cosines of their normals are l , m , 0 and 
∴ ∴ 
∴ ∴ 
∴ ∴ Required equation is 
.
