For a pear-shaped conductor shown above, the concentration of charge on the outside is highest at?

The concentration of charge on the outside of a pear-shaped conductor is highest at the pointy end of the pear shape, which we will label as "X". This is because charges on a conductor will always distribute themselves as far away from each other as possible, in order to minimize their electrostatic potential energy. In the case of a pear-shaped conductor, the charges will distribute themselves so that they are as far away from each other as possible, while still remaining on the surface of the conductor. At point X, the curvature of the surface of the conductor is greatest, which means that the charges on the surface will be more tightly packed together than they would be at any other point on the surface. This results in a higher concentration of charge at point X compared to points Z, Y, and K. Therefore, the concentration of charge on the outside of a pear-shaped conductor is highest at point X.
