Question

potential energy of the electron in an orbit of Hydrogen would be.. a) -mv2 b) -e2/r c) -mv2/2 d) -e2/2r​

Answer 1

Answer:

Explanation:

Option B.

-e2/r

Potential energy of the electron in an orbit of Hydrogen would be -e2/r

Hope it helps you

Answer 2

According to Bohr's theory, the formula for calculating the Potential Energy of Hydrogen like species is −27.2(z2/n2)eV−27.2(z2/n2)eV

where z is the atomic number and n is the shell number.

For first shell of hydrogen atom put n=1 and z=1. You will get PE=−27.2eVPE=−27.2eV

PS PE is twice of KE (which has positive sign) in magnitude.

Option B
