Question
A particle moves in a straight line with velocity given by 
(x being the distance described). The time taken by the particle to describe 99 meters is:
Hint:
In this question we have to find t i.e., time taken by the particle to find this we will integrate both sides.
The correct answer is:

A given ray of light suffers minimum deviation in an equilateral prism P. Additional prisms Q and R of identical shape and material are now added to P as shown in the figure. The ray will suffer
As the prisms Q and R are of the same material and have identical shape they combine to form a slab with parallel faces. Such a slab does not cause any deviation.
