A 8.01-nC charge is located 1.87 m from a 4.50-nC point charge. (a) Find the magnitude of the electrostatic force that one charge exerts on the other.(b) Is the force attractive or repulsive?

Respuesta :

Answer:

Explanation:

Given

[tex]q_1=8.01\ nC[/tex]

[tex]q_2=4.50\ nC[/tex]

distance between the charges is given by [tex]d=1.87\ m[/tex]

Electrostatic force between the charges is given by

[tex]F_{12}=F_{21}=\frac{kq_1q_2}{d^2}[/tex]

where k=constant [tex]=9\times 10^{9}[/tex]

[tex]F_{12}=F_{21}=\frac{9\times 10^9\times 8.01\times 4.50\times 10^{-18}}{(1.87)^2}[/tex]

[tex]F_{12}=F_{21}=92.769\times 10^{-9}\ N[/tex]

as both the charges are of similar nature therefore they repel each other
