Electric Force?

Question

Two pellets each with a charge of 1 microcoulomb(10^-6 C) are located 3 cm(.03m) apart. What is the electric force between them? an object of what mass would experience this same force in the earths gravitational field?

Answer 1

F=(kqq)/r^2
F=((9x10^9)(1x10^-6)^2)/(.03)^2
F=10N
F=mg
10=9.8m
m=1.02kg

Answer 2

a million) rigidity on the electron F = m a = 9.a million x10^-31 x 6.3 x10^3 = 5.733 x10^-28 N 2) electric powered container power E = F / e = m a / e = a / ( e / m ) = 6.3 x10^3 / a million.seventy six x10^11 = 3.6 x10^-8 N /C.
