Physics: Exercises with solutions

In this exercise (with solution) you have to calculate the distance between the capacitor plates for a given capacitance and and than use relative permittivity.

In this exercise with solution about the plate capacitor, the capacitance, voltage and energy must be compared with and without dielectric.

The exercise teaches you how to calculate the charge of a thundercloud using the capacitance and E-field in the plate capacitor.

In this problem (with solution) you have to derive the torsion tensor and then the expression for Christoffel symbols with torsion.

Here you practice the properties of the Kronecker delta by simplifying given expressions as much as possible.
