(a) In an experiment a student moves a negatively charged glass rod close to a balloon suspended by a string from the ceiling. The balloon moves towards the glass rod. Circle the diagram representing the charge on the balloon that would result in the balloon moving towards the glass rod. + + + + A B (b) The student then suspended two identical balloons from the ceiling. Each of the balloons had a charge of 1μC and the balloons moved 3 cm apart from each other. Calculate the force of repulsion between the balloons.

Dielectric Constant Of Water
Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.
Electrostatic Potential and Capacitance
An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particles. The electric force is the force which acts between two stationary charges. It is also called Coulomb force.
