Question

A cyclotron is used to acceleration protons. deuterons, $\alpha$-particles etc. If the energy attained, after acceleration, by the protons is $E$, the energy attained by $\alpha$-particles shall be:

• A. $4E$
• B. $2E$
• C. $E$
• D. $E/4$

Answer 1

The correct option is B $2E$

$E=qV$

$E^{\prime }=2qV=2E$

where V is the potential , q is charge and E is energy
