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

The complete question is;

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 speed will keep increasing

D) As it moves farther and farther from Q, its acceleration will keep increasing.

Option C - As it moves farther and farther from Q, its speed will keep increasing.

Explanation:

We are told that when a second positive point charge(q) is released from rest near the stationary charge and it's free to move. Thus, the stationary charge will now exert a repulsive force upon thus second positive point charge and it will go on decreasing because the mobile charge will move away from the stationary charge. Thus, it will have a decreasing but positive acceleration . So we can conclude that it's velocity will keep increasing but it will be at a declining rate.

Thus, the correct answer is;

Option C - As it moves farther and farther from Q, its speed will keep increasing.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
