A test tube of mass 10 grams closed with a cork of mass 1 gram contains some ether . When the test tube is heated the cork flies out under the pressure of the ether gas. The test tube is suspended horizontally by a weight less rigid bar of length 5 cm . What is the minimum velcoity with which the cork should fly out of the tube , so that test tube deseribing a full vertical circle about the point O . Neglect the mass of ether .

A test tube of mass 2m closed with a cork of mass m contains a drop of liquid of negligible mass. When the test tube is heated, the liquid evaporates and the cork flies off under the pressure of the gas. What must be the minimum velocity with which the cork must be ejected such that the test tube describes a full circle of radius R about the pivot? (Assuming test tube as a point object) R 11 (2mm 5

Which is the proper way to heat a liquid in a test tube?

During gas of negligible mass is sealed in a test tube of mass 50 gm with the helo of a stopper of mass 3.5 gm . The test tube is suspended from a fixed point with help of massless string such that the test tube is horizontal and distance between point of suspension and centre of mass of test tube is 25 cm . The test tube is heated to a temperature due to which stopper is ejected out horizontally while test tube completes a vertical circle of radius 25 cm . The minimum velocity with which stopper should be ejected out is
