A positive point charge Q is fixed on a very large horizontal frictionless tabletop. A second positive point charge q is released from rest near the stationary charge and is free to move.
 
  Which statement best describes the motion of q after it is released? A) Its speed will be greatest just after it is released.
  B) Its acceleration is zero just after it is released.
  C) As it moves farther and farther from Q, its acceleration will keep increasing.
  D) As it moves farther and farther from Q, its speed will decrease.
  E) As it moves farther and farther from Q, its speed will keep increasing.

Question 2

How much work must be done to accelerate a particle of mass 2.1  10-14 kg from a speed of 1.5  108 m/s to a speed of 2.5  108 m/s? (c = 3.00  108 m/s)
 
  What will be an ideal response?

The term pharmacology is derived from the Greek words pharmakon("claim, medicine, poison, or remedy") and logos ("study").

Did you know?

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).

Did you know?

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
