let the vector Q is given as

given that

here we know that

now by above equation


so by comparing both sides
b = 0
4c - 3a = 6
also we know that


by solving above equation
a = 12.85 and c = 11.14
so the vector Q is given as

Electrical conductivity
Magnetism
Texture
Hope this helps!
We have that the force between the two charged objects is mathematically given as
F=2.349N
<h3>Magnitude of the force between two charged objects.</h3>
Question Parameters:
Two spheres carry a charge of 1x10^-7 C.
Their centers are <u>separated</u> by 0.7m.
Generally the equation for the Force is mathematically given as

Therefore

F=2.349N
