Question

Physic What is the electric force between the ball and the comb?

A small ball has a charge of –8.5 x 10-6 C.

A comb with a charge of 6.2 x 10-6 C is placed 0.10 m away from the ball.

What is the electric force between the ball and the comb?


3.1 N


52 N


1.3 N


47 N

Answer 1

Answer: It's B. Hope this helps.

Explanation: If it's not that answer, correct me.

Answer 2

Answer is 47 N

Step-by-step explanation:

Apply Coulomb's law

by using the formula

F= kQ1Q2/ r²

you have all the data , you can start with any charge and the distance is there as r and its already in meters for you then calculate
