  2. para un átomo de hidrógeno calcule:1. La Fuerza de atracción entre el núcleo y su electrón • F=Kq1q2/r^2 • =(9X10^9)(1.6X10^9) )(1.6X10^9)/(5X10^-11)^2=9.2X10^-8 N

  3. 2. El campo eléctrico que afecta o "siente" el electrón • E= F/q • =(9.2x10^-8)/(1.6x10^-19)=5.75X10^11 N/C

  4. 3. La velocidad tangencial • V= √qEr/m • = √(1.6X10^9)(5X10^-11)(5.75X10^11 )/(9.1x10^-31) • V= 2248320.496 m/s

  5. 4. El período de rotación de un electrón • W=v/r • W= (2248320.496)/(5x10^-11)= 4.49x10^16 seg^-1 T= 2π/W • T =2(3.1416)/4.49x10^16 seg^-1 • T= 7.19X10^15 seg^-1

  6. 5. La frecuencia de giro(pistas: use la Ley de Coulomb y la Fuerza de Newton para movimiento circular) • F= 1/T f= 1/ 1.39X10^-15 seg^-1
