## Force on a ChargeEdit

When we want to discuss the force on a charge due to a charge distribution, there are two options. The first is a more traditional method: an integral over a volume containing the charge distribution. The second method is less traditional but is easier to do: a surface integral over a special stress tensor.

## Volume Integral VersionEdit

## Electrostatic Stress TensorEdit

## Surface Integral VersionEdit

## The Maxwell Stress TensorEdit

T_{ij} is called the Maxwell Stress Tensor, it has two indices and is not a vector so is given a double arrow.
