Two pellets, each with a charge of 1 microcoulomb, are located 3 cm apart. What is the electric force between
them?
Ans. Force = (9x109) x q1 x q2/d2. Substituting into this inverse-square law we get Force = (9x109) (10-6)( 10-6)/(.03)2 = 10 Newtons.

Two pellets, each with a charge of 1.1 microcoulomb (1.1×10−6 C ), are located 3.2 cm (3.2×10−2 m ) apart.
What's the electric force between them?
To calculate the electric force between two charged pellets, we can use Coulomb's Law, which states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
The formula for Coulomb's Law is:
F = k * (q1 * q2) / r^2
Where:
F is the electric force
k is the electrostatic constant (k = 9 x 10^9 N * m^2 / C^2)
q1 and q2 are the charges of the pellets
r is the distance between the pellets
Given:
q1 = q2 = 1 microcoulomb = 1 x 10^-6 C
r = 3 cm = 0.03 m
Plugging in the values into the formula:
F = (9 x 10^9 N * m^2 / C^2) * ((1 x 10^-6 C) * (1 x 10^-6 C)) / (0.03 m)^2
To calculate the electric force between two charges, you can use Coulomb's Law. According to Coulomb's Law, the electric force (F) between two charges (q1 and q2) is proportional to the product of their charges and inversely proportional to the square of the distance (r) between them.
The formula for Coulomb's Law is:
F = k * |q1 * q2| / r^2
where:
- F is the electric force between the two charges,
- k is the electrostatic constant (k = 9 * 10^9 Nm^2/C^2),
- q1 and q2 are the charges of the two pellets,
- r is the distance between the charges.
In this case, both pellets have a charge of 1 microcoulomb, which is equivalent to 1 * 10^(-6) C. And the distance between them is 3 cm, which is 0.03 meters.
Plugging in the values into the formula:
F = (9 * 10^9 Nm^2/C^2) * |(1 * 10^(-6) C) * (1 * 10^(-6) C)| / (0.03 m)^2
After performing the calculation, the electric force between the pellets should be obtained.
