Do you mean when objects move as a direct result of the passing wave?
Waves have energy and constitute a force, just like wind. Therefore that
force is able to move objects in its path.
Answer:
Explanation:
F1 = (Kq1 q2)/r^2
Where K = 9x10^9NmC-2
F1 = (9×10〗^9×2×5×〖10〗^(-9))/2^2 =22.5N
F2= (Kq_2 q_3)/r^2
F2 = (9*〖10〗^9×5×〖10〗^(-9)×5)/2^2 =25N
F3= (Kq_3 q_4)/r^2
F3 = (9*〖10〗^9×5*〖10〗^(-9)×-4)/2^2 =-7.2N
Net horizontal force F = F2 – F1
F = 25 – 22.5 = 2.5N
Net force in 5nC = √((〖7.2〗^2 )+〖2.5〗^(2 ))=7.62N
