← Assertion (A): A simple cyclotron is not used to accelerate electrons to very high energy. Reason (R): As an electron gets near the speed of light its mass grows, so its time for a turn changes and it falls out of step.
A proton goes round in a uniform field of 0.54 T. How long does it take for one turn? →
