What is potential energy ? State its unit.
Potential Energy : (P.E. or U) “The energy possessed by a bo tody due its position above the ground . or change in state.” UNIT : Unit of P.E. = S.I. UNIT OF ENERGY = Joule (J)
S.I unit of kinetic energy is joule(J).What is the S.I unit of potential energy?
Supposing the energy of fourth shell for H-atom is 50 a.u.(arbitrary unit) what would be its ionization potential?
What is the energy of a hydrogen atom in the first exc ited state if the potential energy is taken to be zero in the ground state ?
