Answer:
-13.09 N
Explanation:
Hello!
With Coulomb's law, the force of attraction between two charges can be calculated:
F=(K*q_1*q_2)/r^2
K=9*〖10〗^9 (N*m^2)/C^2
9,9 cm = 0,099 m
-2,3µC= -2,3*〖10〗^-6 C
6,2µC= 6,2*〖10〗^-6 C
By simplifying units the force remains in Newton.

Answer: wavelength= 2.842m
Explanation:
wave speed C= frequency × wavelength
Wavelength= C/ frequency
= 2.998× 10exp8/ 105.5×10exp6Hz
Wavelength= 2.842m
Goodluck...
