The force acting between two charged particles a and b is 5.2  *  10è¢ newtons. charges a and b are 2.4  *  10èæ meters apart. if the charge on particle a is 7.2  *  10è§ coulombs, what is the charge of particle b? (k = 9.0  *  10© newton·metersæ/coulombæ)

The correct question is shown in the image attached with.

This is a question of Physics. Concept of Coulomb Force is used here. The formula for the Coulomb Force is:



F, k, r and  are known and we are to find  . Using the given values, we can write:



Simplifying and solving the equation for we get:

The charge of particle B = Coulomb.

Afraidsugar lol it’s the third one
