STATEMENT -1 : For an observer looking out through the window of a fast moving train , the nearby objects appear to move in the opposite direction to the train , while the distant objects appear to be stationary .
STATEMENT - 2 : If the observer and the object are moving at velocities ` vec v_(1)` and `vec v_(2)` respecttively with refrence to a laboratory frame , the velocity of the object with respect to a laboratory frame , the velocity of the object with respect to the observer is `vecv_(2) - vecv(1) ` .
(a) Statement -1 is True, statement -2 is true , statement -2 is a correct explanation for statement -1
(b) Statement 1 is True , Statement -2 is True , statement -2 is NOT a correct explanation for statement -1
(c) Statement - 1 is True , Statement -2 is False
(d) Statement -1 is False, Statement -2 is True

Options

A. If both assertion and reason are correct and reason is a correct explanation of the assertion.
B. If both assertion and reason are correct but reason is not the correct explanation of assertion.
C. If assertion is correct but reason is incorrect
D. If assertion is incorrect but reason is correct.

Answer

b

Explanation

Both the statements are true but statement 2 is not the correct explanation to the statement 1. Relative velocity of near stationary object and as well as far stationary objects is same with respect to the moving train but still brain perceives far objects nearly stationary.
When some object movies in front of our eyes then observed displacement of object is proportional to the displacement of image of object formed by eye lens on the retina . When object at a very large distnace moves in front of eyes then displacement of correspoding image on retina remains proporitionally very small and hence the object appear stationary.
