(1) A rheostat can be used as a potential divider (2) Kirchhoff's second law represents energy conservation (3) Wheatstone bridge is the most sensitive when all the four resistances are of the same order of magnitude. (4) In a balanced wheatstone bridge if the cell and the galvanometer are exchanged, the null point is disturbed. Ans. (4) The following observations were taken for determining surface tensiton T of water by capillary method : Diameter of capilary, D = 1.25 × 10–2 m rise of water, h = 1.45 × 10–2 m Using g = 9.80 m/s2 and the simplified relation T = rhg 2 × 103 N/m, the possible error in surface tension is closest to : (1) 2.4% (2) 10% (3) 0.15% (4) 1.5% Ans. (4) In amplitude modulation, sinusoidal carrier frequency used is denoted by c and the signal frequency is denoted by m. The bandwidth (m) of the signal is such that m << c. Which of the following frequencies is not contained in the modulated wave ? (1) m + c (2) c – m (3) m (4) c Ans. (3) A diverging lens with magnitude of focal length 25 cm is placed at a distance of 15 cm from a converging lens of magnitude of focal length 20 cm. A beam of parallel light falls on the diverging lens. The final image formed is : (1) real and at a distance of 40 cm from the divergent lens (2) real and at a distance of 6 cm from the convergent lens (3) real and at a distance of 40 cm from convergent lens (4) virtual and at a distance of 40 cm from convergent lens. Ans. (3)   |
