An ideal gas is kept in a long cylindrical vessel fitted with a frictionless piston of cross-sectional area 10cm2 and weight 1kg. The length of the gas column in the vessel is 20cm. The atmospheric pressure is 100kPa. The vessel is now taken into a spaceship revolving round the earth as a satellite. The air pressure in the spaceship is maintained at 100kPa. Find the length of the gas column in the cylinder.
The earth revolves round the sun due to gravitational attraction. Suppose that the sun and the earth are point particles with their existing masses and that Bohr's quantization rule for angular momentum is valid in the case of gravitation. (a) Calculate the minimum radius the earth can have for its orbit. (b) What is the value of the principal quantum number n for the present radius? Mass of the earth = 6.0 × 10-24kg. Mass of the sun = 2.0 × 1030kg, earth-sun distance = 1.5 × 1011m.
Two fixed, identical conducting plates $(\alpha\ \&\ \beta)$, each of surface area S are charged to -Q and q, respectively, where Q > q > 0. A third identical plate $(\gamma)$, free to move is located on the other side of the plate with charge q at a distance d (Fig.). The third plate is released and collides with the plate $\beta$. Assume the collision is elastic and the time of collision is sufficient to redistribute charge amongst $\beta\ \&\ \gamma$.
Find the electric field acting on the plate $\gamma$ before collision.
