Answer:
4N
Explanation:
because the net force is greater in the right direction
c.charge due to the reaction process between the two
For a standing wave on a string, the wavelength is equal to twice the length of the string:

In our problem, L=50.0 cm=0.50 m, therefore the wavelength of the wave is

And the speed of the wave is given by the product between the frequency and the wavelength of the wave:
