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:

$E_t=2.14*10^{-13}J$

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

$E_t=K.E+2me$

$E_t=5*10^{-14}*0.510 998 950 00*1.6 * 10^{-19}$

$E_t=2.14*10^{-13}J$
