Point-B has equal distance both from negative charge and positive charge. 
When a -ve test charge is placed at B , repulsive force is directed along NW direction and
attractive force is directed along SW direction.
 
Since these two forces are equal in magnitude, resultant is directed exacly along West.
 
All other points, magnitude of repulsive and attractive forces different and also acting in different direction. 
Hence resultant force will not be exactly along west

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
