5. A small sphere with mass 1.50 g hangs by a thread between two parallel vertical plates that are 5.00 cm apart. The sphere carries charge q=8.90x10—6 C. The plates are insulating, and left and right have uniform surface charge densities +σ and −σ, respectively. The space between the plates is filled with air. Find the value of ♂ and the magnitude of the potential difference AV which lead the thread to assume an angle of 30.0° with respect to the vertical.
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.
