Figure shows sequence of large number of photograph of on object moving vertically under gravity. A motion picture of this photograph is run backward. `overset(circ)overset(circ)overset(circ)overset(circ)overset(circ)overset(circ)(circ)` Statement-1: In time reversal sequence the gravitational acceleration will appear to be upward. Statement-2: A time reversal operation changes every `vec(v)to -vec(v)`.A. Statement -1 is true, statement-2 is true and statement-2 is correct explanation for statement-1B. Statement-1 is true, statement-2 is true and statement -2 is NOT the correct explanation for statement-1C. Statement-1 is true, statement-2 is false.D. Statement-1 is false, statement -2 is true.
