Acommonly used potential-energy function for the interaction of two molecules is the lennard-jones 6-12 potential u(r)=u0[(r0r)12−2(r0r)6] where r is the distance between the centers of the molecules and u0 and r0 are positive constants. the corresponding force f(r) is given by equation f(r)=12u0r0((r0r)13−(r0r)7).

What is the fate of the electrons that interact with a specimen in an electron microscope?

Consider two metallic rods mounted on insulated supports. one is neutral, the other positively charged. you bring the two rods close to each, but without contact, and briefly ground the the neutral rod by touching it with your hand. show answer correct answer what would be resulting charge (if any) on the initially neutral rod
