27
Step-by-step explanation:
Where’s the graph ? I think you’ll need to show the graph in order for us to help you
#9) b^4 - 81 = (b^2)^2 - 9^2 = (b^2+ 9)(b^2- 9)<span>
#5) m^4-1 = (m^2)^2 - 1 = </span>(m^2 + 1)(m^2- 1)<span>
#10) 81x^4-16 = (9x^2)^2 - 4^2
= (9x^2 +4)(9x^2 - 4)
</span>
Answer:
The charge needed will be 
Step-by-step explanation:
The equation of the electric force is given by:
We have the force 
and the distance r = 200. k is the Coulomb constant. Q and q are the charges.
We assume we have the same charge of the particles, so we have:
Therefore, the charge needed will be
