Which of the following particles can't be accelerated in a cyclotron?
(1) Proton `p^(+)` (2) Antiproton `p^(-)`
(3) Alpha particle `alpha^(++)` (4) Positron `e^(+)`

Text Solution

Verified by Experts

We always make you learn that electrons can.t be accelerated in a cyclotorn and most of the time with electron, the only thing which strikes your mind is that it. Has negative charge (it doesn.t strike your mind that an electron has small mass and the reason because of whic we do not accelerated electron is not its negative cahrge rather its small mass) and because of whcih you may be tempted to mark ans (2) because rest all are positive charge -but that.s incorrect choice. You know the reason because of whcih we do not accelerated electrons is its small mass and hence the correct choice is 4. Postron is the anti particle of electron and hasd the same mass but opposite charge.
