Three identical charges are placed on three vertices of a square. If the force acting between $q_{1}$ and $q_{2}$ is $F_{12}$ and between $q_{1}$ and $q_{3}$ is $F_{13}$ then $\frac{F_{13}}{F_{12}} =________.$

Options:

Answer:

Solution:

$F_{12} = \frac{K q^{2}}{a^{2}}$

$F_{13} = \frac{K q^{2}}{{(\sqrt{2} a)}^{2}} = \frac{K q^{2}}{2 a^{2}}$

$\frac{F_{13}}{F_{12}} = \frac{1}{2}$
