How to solve problems with Body in Static equilibrium

1 Comment / Physics, Tips and tricks / physicscatalyst

Draw a neat diagram of the system.

Firstly consider the origin of the forces acting on the each object.To do this find out the field forces acting on the each object.Wherever contact in available account the contact force carefully

Isolate the object being analyzed. Draw a free-body diagram and then show
and label all external forces acting on the object, indicating where those forces are applied.This way there will not any confusion about the force acting on each object.

Difference between insulators and conductors with Examples

1 Comment / Physics / physicscatalyst

Insulators have very wide forbidden energy gap nearly of the order of 5eV or more.
Because of this very high energy gap it becomes impossible for electrons present in valence band to cross the gap and reach to the conduction band and this makes electrical conduction a practical impossibility in insulators at room temperature.

Conservative and Non conservative forces

1 Comment / Physics, Tips and tricks / physicscatalyst

Some Points about Conservative forces and Non conservative forces
1) Potential energy are defined for Conservative forces
2) An object that starts at a given point and return to the same point,then
net workdone by the conservative force is zero while in case of non conservative force ,it will not be zero
