Every isolated proton in the universe is surrounded by its own   Question options: 1 both of these 2 electric field. 3 neither of these 4 gravitational field.

the radius 7. Consider an electron near the Earth's equator. In which direction will it tend to deflect if its velocity is V a) Directed northward? by Directed upward? earth Into/ tewars the Directed eastward? Socth

2. If two protons lived in a universe where they were both far more massive than protons in our universe, but still had the same charge, calculate the mass that each proton would have if the gravitational force of attraction between them would exactly balance the electrostatic repulsion they experience. (Assume G and ɛ, are the same as in our universe and that the charge on each proton is 1.6 x 10-19 C.)

8:28 93 lecture 1 electricity.. the electric field in space. [Field lines for positive (radially outward) and negative charges (radially inward).] [Field lines for an electric dipole (a pair of charges of equal magnitude but opposite sign)] * The properties of electric field lines: > The direction of the electric field vector E at a point is tangent to the field lines. - The number of lines per unit area through a surface perpendicular to the line is devised to be proportional to the magnitude of the electric field in a given region. - The field lines must begin on positive charges (or at infinity) and then teminate on negative charges (or at infinity). - The number of lines that originate from a positive charge or terminating on a negative charge must be proportional to the magnitude of the charge. - No two field lines can cross each other; otherwise the field would be pointing in two different directions at the same point. H.W 1. Two opposite charges are placed on a line as shown in…
