Two balloons are separated by a distance of 25.5 cm. One balloon is charged with a charge of + 6.25 nC = + 6.25 x 10-9 C and the other balloon is charges with a charge of - 3.5 nC = - 3.5 x 10-9 C. Calculate the magnitude of Coulombic Force between them. Explain what kind of coulombic force will exist between them (attractive or repulsive)?
