Two concentric shells of uniform density having
massesm1 and m2 are situated as shown below.
find the force on a particle of mass m when the particle is
locatedat
a.) r = a
b.) r = b
c.) r = c
the distance r is measured from the center of theshells.

it should be -8.6 cm hope this out

e/c, where e is its total energy

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
