A particle is moving in clockwise sense on the circumference of a circle x 2 + y 2 = 4, it leaves the circle tangentially at a point P and then reflected by a wall parallel to y-axis at A(4, 0). After reflection particle again starts moving along the circle at point Q. R is image of point P in the wall. 
and 
are the area of Δ PAQ and Δ PAR respectively. Then -
A
B
C
D
None
Text Solution
Verified by ExpertsThe correct answer is:
A
Clearly 
= ar ( Δ PAR) = 2ar ( Δ PAM) … (i)
= ar ( Δ PAR) = 2ar ( Δ PAL) ….(ii)
Now ar ( Δ PAL) = ar ( Δ PAM) … (iii)
From (i), (ii) & (iii) we get
=
