Electromagnetic radiation is emitted by accelerating charges. The rate at which energy is emitted from an accelerating charge that has charge q and acceleration a is given by dE dt = q2a2 6pP0c3 where c is the speed of light. (a) Verify that this equation is dimensionally correct. (b) If a proton with a kinetic energy of 6.0 MeV is traveling in a particle accelerator in a circular orbit of radius 0.750 m, what fraction of its energy does it radiate per second? (c) Consider an electron orbiting with the same speed and radius. What fraction of its energy does it radiate per second?

a)  

b)  

c)

Explanation:

From the question we are told that:

Kinetic energy of Proton

Radius

Energy

a)

b)

Generally the equation for acceleration of proton is mathematically given by

Where

Speed of Proton particle is

Therefore

Energy radiated per sec

Therefore the Fraction of its energy  it radiates per second is given as

c)

Generally the equation for acceleration of proton is mathematically given by

Where

Speed of Proton particle is

Therefore

Energy radiated per sec

Therefore the Fraction of its energy  it radiates per second is given as

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
