“Can mass of a charged particle be infinite and if
yes explain how and when?????”
Answer: Please note that charge is independent of speed but mass depends on speed. So of a body of any mass is moving with gradually increasing speeds, its mass goes on increasing as per the theory of relativity (The relativistic mass ) but the charge remains the same.
Therefore, the mass of a charged particle can be infinity.
