When the speed of an electron increases, its specific charge

When the spped of an electron increases, its charge /mass ratio or specific charge decreases.................................................

@ mandeep 
we know that specific charges are e/m 
e/m is inversely proportional to the velocity of the electron ,, therefore as speed of the electron increases , the specific charges decreases . 
HOPE IT HELPS 
ALL THE BEST ..

When speed of a electron is increases it’s specific charge decreases. as e/m is invorsily proportional to electrons velacity.

As per the theory of relativity, as the velocity of electron increases its mass also increases. As specific charge is inversely proportional to mass, as mass increases specific charge decreases. Hence as velocity of electron increases it specific charge decreases
