Electrostatics Question 308

Question: The distance between H+ and Cl ions in HCl molecule is 1.28 Å. What will be the potential due to this dipole at a distance of 12 Å on the axis of dipole [MP PMT 2002]

Options:

A) 0.13 V

B) 1.3 V

C) 13 V

D) 130 V

Show Answer

Answer:

Correct Answer: A

Solution:

V=9×109.pr2

=9×109×(1.6×1019)×1.28×1010(12×1010)2 = 0.13V
