Answer:
<em>a. F = 14 N</em>
<em>b. Since the spheres' charges have different signs, the force is attractive</em>
Explanation:
<u>Coulomb's Law </u>
The electrical force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between the two objects.
Written as a formula:
Where:
q1, q2 = the objects' charge
d= The distance between the objects
The spheres A and B have charges of:
The distance is d=15 cm = 0.15 m.
a. The force is now calculated:
F = 14 N
b. The electrostatic force between charges is repulsive if they have like signs, the force between them is attractive if they have opposite signs.
Since the spheres' charges have different signs, the force is attractive
