Find out the electrostalic force between two point charges placed in air (each of +1 C) if they are separately by 1 m. |
Answer» `F_(e)=(kq_(1)q_(2))/r^(2)=(9xx10^(9)xx1xx1)/1^(2)=9xx10^(9)N` From the above result, we can say that 1 C charge is too large to realize. In nature, charge is usually of the order of `muC` |
