i. Excess pressure inside a spherical liquid drop , because there is only one free surface here
ii. In case of spherical meniscus of radius of curvature , also excess pressure because again there is only one free surface.
iii. Excess pressure inside a cylindrical drop of radius . Hence, for a cylindrical bubble in air, excess pressure is , because there exist two free surfaces in this case.
iv. For a spherical bubble in water, excess pressure , as there is only one free surface.
Hence, all the four options are correct.

Texts: 1. Two particles of mass m1 and m2 interact via an inverse-square force F12 = -kr/r², where r = r₂ - r₁ is the relative vector. There are no external forces. a) Deduce the equations of the trajectories r₁(0) and r₂(0) of the particles relative to the CM frame in polar form. b) For an attractive force (k > 0), plot the trajectories relative to the CM frame for the following masses and eccentricities: i. m₁ = m₂ and e = 0.65; ii. m₁ = 2m₂ and e = 2; iii. m₁ = 2m₂ and e = 6.0. c) For a repulsive force (k < 0), plot the trajectories for: i. m₁ = m₂ and e = 4; ii. m₁ = 2m₂ and e = 8. 2.

Refer to diagram 1. A positive answer means work is done by the system; a negative answer means work is done on the system. The pressure is 11.5 atm and the volume is 717 liters. The P-V diagram for this process is a straight line. Find the total work done by the system, in KJ. A 5 kg of a monatomic ideal gas (mass number 671) is slowly changed from pressure 11.5 atm and volume 893 liters to pressure 44.3 atm and volume 717 liters.
