Astatic electric field with spherical symmetry is described by , where c and r are constants. rcre r, where e and r are constants. (a) determine the charge density, p(r). [8 points (b) find the total charge of the system. [8 points] (c) find the static electric potential v(r). [8 points] (d) find the total energy stored in the electric field. [8 points] (e) a small test charge +q is released at rest at the radial location r r. what is the kinetic energy when it reaches a point far away?

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

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.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?
