A 20 C positive charge is held a distance x away from a stationary 10 C negative charge. The positive charge is released and accelerates toward the negative charge, attaining a velocity of 50 m/s when it reaches a distance of 0.5x from the 10 C charge. How far apart were the two particles initially?

Distance between the two charges is given as

where m = mass of the charge

Explanation:

As we know that the charge is released from rest

Here it will gain kinetic energy when it reaches near to other stationary charge.

So we can say that change in electrostatic potential energy = gain in kinetic energy of the charge

So we have

so we have

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..
