Electromagnetic radiation is emitted by accelerating charges. The rate at which energy is emitted from an accelerating c

[answerhappygod]

Electromagnetic radiation is emitted by accelerating charges.
The rate at which energy is emitted from an accelerating charge
that has charge qq and acceleration aa is given
by dE/dt=(q2a2)/(6πϵ0c3)
where c is the speed of light.
1. If a proton with a kinetic energy
of 5.7 MeV is traveling in a particle accelerator in
a circular orbit with a radius of 0.760 m, what
fraction of its energy does it radiate per second?
2. Consider an electron orbiting with the same speed and
radius. What fraction of its energy does it radiate per second?
