Two charged particles having charge $2.0 \times {10}^{–8}C$. each are joined by an isolating string of length 1 m and the system is kept on a smooth horizontal task. The tension in the string

Given data: two charged particles having charge each is $2.0\times {10}^{-8}C$ connected to the other by a 1m long isolating string, and the system is kept on a smooth horizontal task.

Concept solution: coulomb’s law

Detailed solution:

We know that coulomb’s law,

 $F=\frac{q^2}{4\pi {\epsilon }_0{r}^2}$ 

 $F=3.596\times {10}^{-6} \mathrm{N}$
