Your hand is not capable of moving fast enough for sound to come out of it.
Explanation:
a) From Coulombs law,
F = (kq1q2)/r²...............1
F = 10 N
r = 10m
k = 9 × 10^9 m/F
q1 = q2
from equation 1, make q the subject
q = (Fr²)/2k
q = (10×10²)/(2×9×10^9)
q = 1000/1.8×10^10
q = 5.556×10^-8 C
b) K = k/ko
k = Kko = 10times permittivity of free-space
Goodluck
