STATEMENT-1: A charged particle is accelerated by a potential difference of V volts. It then enters perpendicularly to a uniform magnetic field. It rotates in a circle. Its angular momentum about centre is say L. Now if V is doubled, L also becomes two times because
STATEMENT-2: If V is doubled, kinetic energy will become two times and therefore, L also becomes two times.
