Question

E(Total Energy)=Eo(Minimum Energy reqd. for the electron)+K.E(kinetic Energy of Photo electron)
hv=hv0 + 1/2 mv2
6.6*10-34*(3.2 * 1016) =Eo+ K.E

2.112*10-17 =Eo+ K.E......................(1)

6.6*10-34*(2*1016) =Eo+ 2*K.E.

1.32*10-17=Eo+ 2 K.E .......................(2)

solving equation (1) and (2):
Eo=2.904*10-17 jum i just talked with u for a day i need time to tell

Answer 1

Answer:

E(Total Energy)=Eo(Minimum Energy reqd. for the electron)+K.E(kinetic Energy of Photo electron)

hv=hv0 + 1/2 mv2

6.6*10-34*(3.2 * 1016) =Eo+ K.E

2.112*10-17 =Eo+ K.E......................(1)

6.6*10-34*(2*1016) =Eo+ 2*K.E.

1.32*10-17=Eo+ 2 K.E .......................(2)

solving equation (1) and (2):

Eo=2.904*10-17
