Recently I studied the concept of cyclotron. In the limitations part of the topic, it was mentioned:

The mass of the particle increases with increase in number of revolutions.

The book had given the formula: $$m=\frac { { m }_{ 0 } }{ \sqrt { 1-\frac { { v }^{ 2 } }{ { c }^{ 2 } } } } $$

I couldn't understand how the mass of the particle increases. Can anyone explain me why this happens? Is there a method to derive the above equation?

Talking about what I've tried, I couldn't think of a concept with which I could proceed.

Thanks.

The formula that you have been given has to do with relativity. As a particle continues to move faster and faster, its mass/energy increases by a factor called \gamma .

With each half revolution in the cyclotron, the velocity increases and so in turn does the mass/energy of the particle.
