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
