Answer:
Force will be 7.97 N
Explanation:
We have given that earth is at s distance of 42000 km from the earth center
So r = 42000 km = 42000000 m
Mass m = 1500 kg
Angular velocity of earth 
We have to find the force
We know that force is given by

Answer:
Datos:
q1 = -50 μC = 
q2 = +30 μC = 
F = 10 N
a) x si la <em>F = 10N</em>
Aplicando la Ley de Coulomb:
x =
=
= 1,162m
b) x si la <em>F = 20 N</em>
x=<em> </em>
<em> </em>= 0,822m
c)x si la <em>F = 50 N</em>
x =
= 0,520m
