If we put negative charge between two similar positive charges then what is it's equilibrium? And how?​

Physics

Gnesinka [82]3 years ago

Your question has been heard loud and clear.

Well it depends on the magnitude of charges. Generally , when both positive charges have the same magnitude , their equilibrium point is towards the centre joining the two charges. But if magnitude of one positive charge is higher than the other , then the equilibrium point will be towards the charge having lesser magnitude.

Now , a negative charge is placed in between the two positive charges. So , if both positive charges have same magnitude , they both pull the negative charge towards each other with an equal force. Thus the equilibrium point will be where the negative charge is placed because , both forces are equal , and opposite , so they cancel out each other at the point where the negative charge is placed. However if they are of different magnitudes , then the equilibrium point will be shifted towards the positive charge having less magnitude.

Thank you

How is wave movement affected by the various mediums it may travel through?
Juliette [100K]

Answer:

speed is affected by the medium in wich the wave travels.

Explanation:

The speed of a wave is affected when traveling in different medium, depending on the medium in which the wave travels it can go faster or slower, or not even be able to travel in that medium.

For light waves, the denser the medium through which the wave travels, the slower it will go through it, as there is more resistance to the light particles.

And in waves like sound, which instead of particles is a vibration or disturbance in the medium, they travel faster in denser mediums such as metal, because the disturbance is transmitted more efficiently thanks to how close together that the particles are in the metal, This is why sound does not travel in a vacuum; there are not even particles to transmit the vibration.

A 0.0450-kg golf ball initially at rest is given a speed of 25.0 m/s when a club strikes. If the club and ball are in contact fo
LuckyWell [14K]

Answer:

Average force, F = 562.5 N

Explanation:

Mass of the golf ball, m = 0.045 kg

Initially, it is at rest, u = 0

Final speed of the ball, v = 25 m/s

The club and the ball are in contact for, t=2\ ms=2\times 10^{-3}\ s

We need to find the average force acting on the ball. It can be calculated using the formula as :

F\times t=m(v-u)

F=m\dfrac{v-u}{t}

F=0.045\times \dfrac{25}{2\times 10^{-3}}  

F = 562.5 N

So, the average force acting on the ball is 562.5 N. Hence, this is the required solution.

Two resistors, A and B, are connected in a series circuit with a battery. The resistance of A is twice that of B. Which resistor
IgorC [24]

Answer:

A dissipates more power.

Explanation:

  • In a series circuit, the current is the same at any point in it.
  • The power dissipated in any resistor follows Joule's law, as follows:

        P = I^{2} * R

  • So, for a given current, the power is directly proportional to the resistance of the resistor.
  • In this case, as resistor A has twice the resistance of resistor B, A dissipates twice more power than B.
