1. Consider two satellites S and S with periods of revolution 1hr. and 8 hr. respectively revolving around a planet in circular orbits. The ratio of angular velocity of satellite S to the angular velocity of satellites S2 is: (a) 1:8 (b) 1:4 (c) 2:1 (d) 8:1 2. Given below are two statements: 3. 4. Statements I: Two photons having equal linear momenta having equal waelengths Statements II: If the wavelength of photon is decreases, then the momentum and energy of a photon will also decrease. In the light of the above statements, choose the correct answer from the options given below. (a) Both Statement I and Statement II are false (c) Both statement I and Statement II are true (b) Statement I is false but Statement II is true (d) Statement I is true but Statement II is false. A cell E of emf 6V and internal resistance 202 is connected with another cell E2 of emf 4V and internal resistance 82 (as shown in p the figure). The potential difference across points X and Y is: (a) 10.0V (b) 2.0V (c) 5.6V Two equal capacitors are first connected in series and then in parallel. The ratio of the equivalent capacities in 6V, 20 4V, 80 E E (a) 4:1 (b) 1:2 (c) 1:4 (d) 2:1
