A soap bubble of radius , surface tension exists in equilibrium in vacuum. A monoatomic gas is trapped inside the soap bubble. Charge is given to bubble such that bubble expands from radius a to radius under reversible adiabatic condition. If surface charge density on the bubble surface is found to be . Find the value of are positive co-primes)
View answer and explanation
Correct option: A
4
Option A (4) is correct because it involves applying the adiabatic process equation, surface tension, and electrostatic pressure to find the relationship between charge and radius.

With the increase in temperature viscosity of a liquid -
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: When you squeeze one end of a tube to get toothpaste out from the other end, Pascal's principle is observed.
Reason R: A change in the pressure applied to an enclosed incompressible fluid is transmitted undiminished to every portion of the fluid and to the walls of its container.
In the light of the above statements, choose the most appropriate answer from the options given below. Hydraulic lifts and hydraulic brakes are based
on As the temperature of a liquid is raised, the coefficient of viscosity A horizontal pipe of cross-sectional diameter 5 cm carries water at velocity of . The pipe is connected to a smaller pipe with a cross-sectional diameter 4 cm. the velocity of water through the smaller pipe is If two soap bubble of different radii are connected by a tube
