Previous 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) Next Question: In the core of nuclear fusion reactor, the gas becomes plasma because of (A) strong nuclear force acting between the deuterons (B) Coulomb force acting between the deuterons (C) Coulomb force acting between deuteron-electron pairs (D) the high temperature maintained inside the reactor core
