Two long straight parallel lines, 1 and 2, carry uniform positive linear charge densities. The charge density on line 2 is twice as great as the charge density on line 1.
 
  The locus of points where the electric field due to these lines is zero is A) along a line between the lines closer to line 2 than line 1.
  B) at a point midway between the lines.
  C) along a line perpendicular to lines 1 and 2.
  D) along a line between the lines closer to line 1 than line 2.

Question 2

A 15-F air-filled capacitor is connected to a 50-V voltage source and becomes fully charged. The voltage source is then removed and a slab of dielectric that completely fills the space between the plates is inserted.
 
  The dielectric has a dielectric constant of 5.0. (a) What is the capacitance of the capacitor after the slab has been inserted? (b) What is the potential difference across the plates of the capacitor after the slab has been inserted?

Certain chemicals, after ingestion, can be converted by the body into cyanide. Most of these chemicals have been removed from the market, but some old nail polish remover, solvents, and plastics manufacturing solutions can contain these substances.

Did you know?

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids. Now it is known that peptic ulcers are predominantly caused by Helicobacter pylori, a spiral-shaped bacterium that normally exist in the stomach.

Not getting enough sleep can greatly weaken the immune system. Lack of sleep makes you more likely to catch a cold, or more difficult to fight off an infection.

Did you know?

People with alcoholism are at a much greater risk of malnutrition than are other people and usually exhibit low levels of most vitamins (especially folic acid). This is because alcohol often takes the place of 50% of their daily intake of calories, with little nutritional value contained in it.

Did you know?

Lower drug doses for elderly patients should be used first, with titrations of the dose as tolerated to prevent unwanted drug-related pharmacodynamic effects.
