A negative charge of -2x10-5 C and a positive charge of 4x10-6 C are separated by a distance of 4 mm. What is the force on the negative charge?

Coulomb's Law     F= k q1 q2 / d^2         k=Coulomb's constant = 9.0 x 109 N m2 /C2

 

                             q1 =-2 x 10-5       q2 = 4 x 10-6   C        d = .004   m           Plug in these numbers to get the force exerted in Newtons
