Question

A positron is a particle that has the same mass but opposite charge of an electron. An electron and a positron are shot directly toward each other by a particle accelerator. They start very far from each other, each with a kinetic energy of

Answer:

`E_t=2.14*10^(-13)J`

Step-by-step explanation:

From the question we are told that:

Kinetic energy
`K.E=5*10^(-14)`

Generally, the equation for Total Energy is mathematically given by

`E_t=K.E+2me`

Where

Mass of an electron in MeV

`m=0.510 998 950 00 MeV`

And

Electron Charge

`1.6 * 10^(-19)`

Therefore

`E_t=K.E+2me`

`E_t=5*10^(-14)*0.510 998 950 00*1.6 * 10^(-19)`

`E_t=2.14*10^(-13)J`
