A positively charged particle of mass 7.27E-8 kg is traveling due east with a speed of 85.2 m/s and enters a 0.330 T uniform magnetic field. The particle moves through one-quarter of a circle in a time of 2.09E-3 s, at which time it leaves the field heading due south. All during the motion the particle moves perpendicular to the magnetic field. What is the magnitude of the magnetic force acting on the particle?

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption
