A fixed system of charges exerts a force of magnitude 9.0 N on a 3.0 C charge. The 3.0 C charge is replaced with a 10.0 C charge. What is the exact magnitude of the force (in N) exerted by the system of charges on the 10.0 C charge?

Answer:

30 N

Explanation:

We are given that

Force,F =9 N

Charge,q=3 C

We have to find the exact magnitude of the force(in N) exerted by the system of charges on the 10.0 C.

We know that

[tex]E=\frac{F}{q}[/tex]

Using the formula

[tex]E=\frac{9}{3}=3 N/C[/tex]

Now, charge=10 C

The electric field remains same then

[tex]F=3\times 10=30 N[/tex]

Hence, the exact magnitude of the force exerted by the system of charges on the 10 C=30 N
