hello to all(adsbygoogle = window.adsbygoogle || []).push({});

here is a problem i designed myself. i don't know whether it can be solved.

Question:

Consider NaCl lattice of edge length 'x' m. Let Na+ carry +1 C and each Cl- carry -1 charge. Calculate Poisson's ratio of NaCl crystal. Assume no heat loss when deformation takes place.

Other questions (easy):

1) Calculate the locus of a point which moves such that the sum of reciprocals of potentials due to two charges separated 'd' distance apart is constant.

I will post other questions later. I will try to come up with a soln. for the Poisson's ratio problem.
