Question

A proton at rest has charge e. When it’s moves with high speed V its charge is
a) e b)πe c)∆e X π d) √2 X e​

Answer 1

Given info : A proton at rest has charge e. it moves with high speed v.

To find : its new charge will be

solution : according to the property of charge invariance, the magnitude of charge doesn't change with speed or frame of reference. it is the mass which varies with speed which is found by Einstein's mass-energy theory.

hence, the charge of proton remains constant, when it moves with high speed v.

therfore the charge of proton is e. so the correct option is (a) e.

Answer 2

Charge of Proton is ‘ e ’ .

option (a) is the correct answer
