Interatomic Force Constant

The dimensions of inter atomic force constant are

If young's modulus of iron be 2xx10^(11) Nm^(-2) and interatomic distance be 3xx10^(-10) m^(-2) , the intertomic force constant will be (in N//m )

The mean distance between the atoms of iron is 3xx10^(-10) m and interatomic fore constant for iron is 7 N//m . The Young's modulus of elasticity for iron is

The interatomic forces of attraction present in noble gas are __________.

The value of electrostatic force constant in free space is ……… .

In solids interatomic forces are

A : Static friction force is a self adjusting force. R : The interatomic forces at the point of contact give rise to friction between the surfaces.

Vibrational kinetic energy is insignificant at low temperatures. Interatomic forces are responsible for vibrational kinetic energy.
