Cousin throckmorton is playing with the clothesline. one end of the clothesline

Cousin throckmorton is playing with the clothesline. one end of the clothesline is attached to a vertical post. throcky holds the other end loosely in his hand, so that the speed of waves on the clothesline is a relatively slow 0.740m/s . he finds several frequencies at which he can oscillate his end of the clothesline so that a light clothespin 43.0cm from the post doesn't move. what are these frequencies?

G=6.66\times 10^{-11}\ m^3kg^{-1}s^{-2}

Explanation:

The centripetal acceleration of the Moon around the Earth is, a_c=2.74\times 10^{-3}\ m/s^2

Mass of the Earth, M=5.97\times 10^{24}\ kg

The mean distance between the centers of the Earth and Moon, r=3.81\times 10^{8}\ m

The centripetal acceleration of the Moon around the Earth is given by the formula as :

a=\dfrac{GM}{r^2}

G=\dfrac{ar^2}{M}

G=\dfrac{2.74\times 10^{-3}\times (3.81\times 10^{8})^2}{5.97\times 10^{24}}

G=6.66\times 10^{-11}\ m^3kg^{-1}s^{-2}

Hence, this is the required solution.
