Electric forces between two charged objects tend to be much stronger in magnitude than the attractive gravitational force between them. Two particles of masses 9 kg and 8.61 kg and charges 8.34 μC and −1.91 μC respectively are separated by a distance 25.1 cm. Find the magnitude of the ratio of the gravitational to electric forces between them.
