Answer:
the speed of the fluid in the wider section of the pipe is 1m/s.
Explanation:
By equation of continuity we can write (for ideal (non-viscous, in-compressible).
A_1,A_2 are areas of the pipe at inlet and outlet of the pipe.
_1
Here, d_1 , d_2 are diameters of inlet and outlet, also v_1, v_2 are velocities at inlet and outlet.
putting values we get
solving we get
The magnitude of <em>electrical</em> force on charge due to the others is 0.102 newtons.

How to calculate the electrical force experimented on a particle</h3>
The vector <em>position</em> of each particle respect to origin are described below:
Then, distances of the former two particles particles respect to the latter one are found now:
The resultant force is found by Coulomb's law and principle of superposition:
(1)
Please notice that particles with charges of <em>same</em> sign attract each other and particles with charges of <em>opposite</em> sign repeal each other.
(2)
Where:
- - Electrostatic constant, in newton-square meters per square Coulomb.
- , , - Electric charges, in Coulombs.
- , - Distances between particles, in meters.
- , - Unit vectors, no unit.
If we know that , , , , , , and , then the vector force on charge is:
And the magnitude of the <em>electrical</em> force on charge (), in newtons, due to the others is found by Pythagorean theorem:
The magnitude of <em>electrical</em> force on charge due to the others is 0.102 newtons.
