To find the magnitude of the resulting force between the two objects, use Coulomb's Law:
 11ec0fda_9981_cb70_a67f_9928508e61bf_NR0004_00 Q1 = the charge on the point-like object one (unit of measure is Coulomb, C)
Q2 = the charge on the point-like object two (unit of measure is Coulomb,C )
r = the distance between the two objects (unit of measure is meter, m)
k = the proportionality constant (unit of measure is N.m²c² )
Step 1: Convert μC to C (1 μC = 1 x 10-6 C)
75 = 75 x 10-6 C
50 = 50 x 10-6 C
Step 2: Insert the values into the equation
Q1 = 75 x 10-6 C
Q2 = 50 x 10-6 C
r = 4
