SATHEE: Electrostatics Question 680

Electrostatics Question 680

Question: Two positive ions, each carrying a charge q, are separated by a distance d. If F is the force of repulsion between the ions, the number of electrons missing from each ion will be (e being the charge of an electron)

Options:

A) $\frac{4 π ε_{0} F d^{2}}{e^{2}}$

B) $\sqrt{\frac{4 π ε_{0} F e^{2}}{d^{2}}}$

C) $\sqrt{\frac{4 π ε_{0} F d^{2}}{e^{2}}}$

D) $\frac{4 π ε_{0} F d^{2}}{q^{2}}$

Show Answer

Answer:

Correct Answer: C

Solution:

[c] Let n be the number of electrons missing. $F = \frac{1}{4 π ε_{0}} \cdot \frac{q^{2}}{d^{2}} \Rightarrow q = \sqrt{4 π ε_{0} d^{2} F} = n e$

$∴ n = \sqrt{\frac{4 π ε_{0} F d^{2}}{e^{2}}}$
