Example 19.1 Page no 168

In [23]:
#Given                       
h=6.624*10**-34
m=9.1*10**-31
a=10**-10

#Calculation
E1=h**2/(8*m*a**2)

#Result
print"Energy is", round(E1*10**19,1),"*10**-10 J"

Energy is 60.3 *10**-10 J

Example 19.4 Page no 169

In [28]:
#Given
a=10**-9                        #m
m=9.1*10**-31                      #Kg
h=6.63*10**-34                     #J-s

#Calculation
E0=h**2/(8*m*a**2)

#Result
print"Value of E0 is",round(E0*10**20,2)*10**-17,"J"

Value of E0 is 6.04e-17 J

Example 19.5 Page no 169

In [29]:
#Given
x=5*10**-10
a=25*10**-10

#Calculation
P=(2*x)/a

#Result
print"Probability of finding the particle is",P

Probability of finding the particle is 0.4
