Solution
The correct option is C -6.8 eV & -3.4 eV
Kinetic energy, K=−U2 …….. (1)
Hence,
Total Energy = K+U = -K……..(2)
Now, We have K = 3.4 eV
So from equation 1) U = -6.8 eV
And from equation 2) Total energy = -3.4 eV.
Kinetic energy, K=−U2 …….. (1)
Hence,
Total Energy = K+U = -K……..(2)
Now, We have K = 3.4 eV
So from equation 1) U = -6.8 eV
And from equation 2) Total energy = -3.4 eV.
