Explanation:
I think it’s D I am sorry if I am wrong
Answer:
Explanation:
It is given that,
Area of cross section of the pipe,
Area of cross section of the another pipe,
Speed of water in first pipe,
To find,
Speed of the water flowing in the second pipe.
Solve,
Let is the speed of water flowing in the second pipe. The relation between the area of cross section and the velocity is given by the continuity equation. It is given by :
Therefore, the water is flowing in the second pipe at the rate of 8 m/s.
The new force between the charges when the distance become 2d will be F'=4F
<h3>What is electrostatic force?</h3>
When two charged particles are separated by the distance d then the force of attraction or repultion acts on the charged particle depending upon the nature of the charge whether it is positive or negative.
The formula for the electrostatic force is given by
Now if the value of d becomes 2d then the formula will become:
Hence the new force between the charges when the distance become 2d will be F'=4F
