Answer:
Part a)
[tex]m_2 = 4.9 \times 10^7 kg[/tex]
Part b)
[tex]q_1 = q_2 = 5312.6 C[/tex]
Explanation:
Part a)
As we know that both charge particles will exert equal and opposite force on each other
so here the force on both the charges will be equal in magnitude
so we will have
[tex]F = m_1a_1 = m_2a_2[/tex]
here we have
[tex]6.3 \times 10^7(7) = m_2(9)[/tex]
now we have
[tex]m_2 = 4.9 \times 10^7 kg[/tex]
Part b)
Now for the force between two charges we can say
[tex]F = \frac{kq_1q_2}{r^2}[/tex]
now we have
[tex](6.3 \times 10^7)(7) = \frac{(9\times 10^9)q^2}{(24\times 10^3)^2}[/tex]
now we have
[tex]q_1 = q_2 = 5312.6 C[/tex]
