problems in equilibrium and its solutions for physics

(ii) The bar is in in unstable equilibrium when is antiparallel to i.e., when q = 180 o . In this case, the potential is maximum and is given by U = +MB = +0.064..

Let the burner lie on its side as in figure below. Push it slightly and see what happens. On further pushing, the C.G. neither gets raised nor lowered. The burner just rolls maintaining its center of gravity at the same level. Objects like cylinders and cones lying on their side roll because they ..

What makes a body stable? An object is said to be stable if it is steady and well balanced so that when it is pushed slightly it does not topple or fall off easily. Let us try to do a simple experiment or derive the conditions for stability. Experiment 1: Stick three pins close together to the..

When two substances at different temperatures are brought together, heat energy flows from a substance at higher temperature to a substance at lower temperature. The heat flow continues till their temperatures are equalized. At this stage, the substances are said to be in thermal equilibrium..

Place the burner upside down as shown in figure below. A slight push causes the C.G. to be lowered and the burner begins to fall to make the C.G. as low as possible [Figure (b) below)..

Equilibrium of Rigid Bodies - A rigid body is said to be in equilibrium if, both the linear and angular momentum of a rigid body have a constant value. For the equilibrium of a rigid body, the body need not be at rest. However, if it is at rest, it is called the static..

A rigid body is said to be in equilibrium if, both the linear and angular momentum of a rigid body have a constant value. For the equilibrium of a rigid body, the body need not be at rest. However, if it is at rest, it is called the static equilibrium. Conditions for t..

The body should have a broad base. Center of gravity of the body should be as low as possible. Vertical line drawn from the center of gravity should fall within the base of suppo..

1. The Earth's gravitational force causes an acceleration of 5 m/s 2 in a 1kg mass somewhere in space. How much will the acceleration of a 3kg mass be at the same place? Solution: The acceleration produced in any body due to the gravitational pull of the Earth does not depend on the mass ..
