What will be the energy of an electron beam at a depth of 4 cm that had a surface energy of 16 MeV?

Question

The second of these relationships deals with the reduction of the energy of an electron beam as it moves through matter.The energy of an electron beam at a given depth in water may be approximated based on the following relationship.The rate at which an electron beam loses energy is approximately 2 MeV/cm in water.For example, an electron beam with an energy of 10 MeV incident on the phantom surface will have an energy of 6 MeV at a depth of 2 cm in water.
