Modern Physics -- velocity of electron accelerated through 6 Mev
Electron accelerated through 6 Mev. from rest. My Answer was > speed of light
he gave us the formulas of new mass vs old mass at rest.
I just don't get it why is mass increased as well as speed increased even though we're starting from rest
