- A microscopic spherical dust particle of radius r and mass m is moving in outer space at a constant speed v. A wave of light strikes it from the opposite direction of its motion and gets absorbed. Part A) Assuming the particle decelerates uniformly to zero speed in time t, write an equation for the average electric field amplitude in the light.I need help solving this example, thanks a lot for the help!X=8
