Two charged particles are placed at a distance 1.0 cm apart. What is the minimum possible magnitude of the electric force acting o each charge?

$\huge\underline{\underline{\bf \orange{Solution-}}}$

$\large\underline{\underline{\sf Given:}}$

• Two charged particles are placed at a distance (d) = 1m

• Let's say minimum charge be ${\sf q_1\:and\:q_2=1.6×10^{-19}C}$

$\large\underline{\underline{\sf To\:Find:}}$

• Minimum possible magnitude of the electric force acting o each charge?

Electrostatic Force (F) ➝

❏$\large{\boxed{\bf \blue{F=\dfrac{1}{4π\epsilon}×\dfrac{q_1q_2}{r^2} }}}$

$\implies{\rm \red{\dfrac{1}{4π\epsilon}=9×10^9}}$

$\implies{\sf F = 9×10^9×\dfrac{(1.6×10^{-19})^2}{1^2}}$

$\implies{\bf \red{Force( F) = 2.56×10^{-38}N} }$

$\huge\underline{\underline{\bf \orange{Answer-}}}$

Minimum possible magnitude of the electric force acting on each charge is ${\bf \red{2.56×10^{-38}N}}$.
