. As the hydrogen atoms come closer, the attractive force tends to decrease the potential energy of the system. When the potential energy reaches a minimum value, sharing of electrons take place between the two, resulting in a covalent bond. This stage is represented by the distance 'r o ..

The ease of evaporation of a liquid is related to the strength of the attractive forces between the molecules in the liquid. In polar liquids cohesive forces are strong while in non-polar liquids the cohesive forces are very weak and the molecules escape easily. For e..

Elastomers are polymers in which the polymer chains are held by weakest intermolecular forces. These forces permit the polymers to be stretched. A few cross links are introduced between the chains to help the polymer retract to its original position after the ..

Let us consider a body of mass 'm' being raised vertically to a height 'h' as in the figure (1). The work done is mgh. Suppose we take the body along the path as in figure (3). The work done during the horizontal motion is zero. Adding up the work done in the two vertical parts of the pat..

If the work done by a force depends only on the initial and final states and not on the path taken, then it is a conservative force. Examples of conservative force force of gravity coulomb's force in electrostatics the elastic force in a s..

Force of attraction between two bodies of mass m separated by a distance 2d. Let us now calculate the force of attraction when the distance between the bodies is increased three times. Force of attraction between two bodies of mass m separated by a distance 3..

The lines of force or field lines 1) start from positive charges and end at negative charges. In the case of a single charge, they may start or end at infinity. 2) two field lines can never intersect each other. 3) contract longitudinally. 4) exert lateral pressure on one anoth..

The horizontal and vertical components of a force acting on a body are 27 Newtons 36 Newtons. Find the magnitude of the force. => 9 Newtons or 45 Newtons or 63 Newtons or tan -1 ( 4 3 ) Newtons..
