Previous Question: A ball is dropped from a height of 20 m above the surface of water in a lake. The refractive index of water is 4/3. A fish inside the lake, in the line of fall of the ball, is looking at the ball. At an instant, when the ball is 12.8 m above the water surface, the fish sees the speed of ball as (A) 9 m/s (B) 12 m/s (C) 16 m/s (D) 21.33 m/s Next Question: A student performed the experiment of determination of focal length of a concave mirror by u â€“ v method using an optical bench of length 1.5 meter. The focal length of the mirror used is 24 cm. The maximum error in the location of the image can be 0.2 cm. The 5 sets of (u, v) values recorded by the student (in cm) are: (42, 56), (48, 48), (60, 40), (66, 33), (78, 39). The data set(s) that cannot come from experiment and is (are) incorrectly recorded, is (are) option (A) (42, 56) (B) (48, 48) (C) (66, 33) (D) (78, 39)
