Answer to Question #324856 in Electric Circuits for melcasalig

Question

determine the electrical force attraction between to balloons that are charged with the opposite type of charge but the same quantity of charge . The charge on the ballons is 6.0 x 10-7C and they are separated by a distance of 0.50 m

Answer 1

The electrical force of attraction is

$F=k\frac{q_1q_2}{r^2},$

where $k=9\cdot10^9 \space (N\cdot m^2)/C^2;$

$q_1,\space q_2$ - charges on the baloons;

r - distance between the baloons.

So,

$F=9\cdot10^9\frac{6\cdot 10^{-7}\cdot 6\cdot 10^{-7}}{0.5^2}=1.3\cdot 10^{-2}\space N.$
