Question

Object 1 has a charge of -2.3 x 10^-6 and Object 2 has a charge of - 4.2 x 10 ^- 6 C. Calculate the electrostatic force between the two objects if they are 0.099 m apart.

A) 9.76 x 10^-11 N
B) 9.86 x 10^-10 N
C) 8.87 N
D) 0.878 N

Answer 1

The electrostatic force between two charged objects can be calculated using Coulomb's law which is A)
`9.76 x 10^-11 N`

Step-by-step explanation:

The electrostatic force between two charged objects can be calculated using Coulomb's law:

`F = k * (q1 * q2) / r^2`

Where F is the electrostatic force, k is the electrostatic constant
`(9 x 10^9 Nm^2/C^2),` q1 and q2 are the charges of the objects, and r is the distance between them.

Plugging in the values from the question, we get:

F =
`(9 x 10^9 Nm^2/C^2) * ((-2.3 x 10^-6 C) * (-4.2 x 10^-6 C)) / (0.099 m)^2`

= 9.76 x 10^-11 N

So the correct answer is A)
`9.76 x 10^-11 N.`
