Answer:
Most electric charge is carried by the electrons and protons within an atom. Conversely, two protons repel each other, as do two electrons. Advertisement. Protons and electrons create electric fields, which exert a force called the Coulomb force, which radiates outward in all directions.
Answer:
c
Explanation:
a vector quantity has both magnitude and direction
Answer:
Explanation:
We shall apply Pascal's Law in fluid mechanics
According to it , pressure is transmitted in liquid from one point to another without any change .
25 cm diameter = 12.5 x 10⁻² m radius
Area = 3.14 x (12.5 x 10⁻²)²
= 490.625 x 10⁻⁴ m²
Pressure by vehicle
Force / area
13000 / 490.625 x 10⁻⁴
= 26.497 x 10⁴ Pa
5 cm diameter = 2.5 x 10⁻² radius
area = 3.14 x (2.5 x 10⁻²)²
= 19.625 x 10⁻⁴ m²
If we assume required force F on this area
Pressure = F / 19.625 x 10⁻⁴ Pa
According to Pascal Law
F / 19.625 x 10⁻⁴ = 26.497 x 10⁴
F = 19.625 x 26.497
= 520 N
Answer:
F = 3 fo
Explanation:
The electric force is given by Coulomb's law
F = k q₁ q₂ / r²
where k is the Coulomb constant and is equal to 8.99 109
with the initial charge the force is
Fo = k q₁ q₂ / r²
Fo =k q₁ q₂ / r²
In this case it is indicated that charge 1 is changed by the lithium atom a = 3 P
we substitute
F = k 3p p / r²
F = 3 (k p² / r²)
F = 3 fo
we see that the charge increases by three orders of magnitude
