Question

The electric dipole moment of an electron and a proton $4.3 \,nm$ apart is

• A. $ 6.88 \times 10^{ - 28}\, cm$
• B. $ 2.56 \times 10^{ - 14}\, C^2/m$
• C. $ 3.72 \times 10^{ - 28} \,C/m$
• D. $ 1.1 \times 10^{ - 46} \,C^2\, m$

Answer 1

Answer: (A)

The electron dipole moment is equal to
$p=1.6 \times 10^{-19} \times 4.3 \times 10^{-9} $
$=6.88 \times 10^{-28} \,cm$
