Three identical point charges ( 2.0 nc) are placed at the corners of an equilateral triangle with sides of 2.0-m length. if the electric potential is taken to be zero at infinity, what is the potential at the midpoint of any one of the sides of the triangle?

i think it's 35 meters

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.
