Question

Two charges, one with a charge of +10.0 x 10-6 C, the other with a charge of -3 x 10-6 C exert a force on each other with a magnitude of 1.7 Newtons on each other. Is this a repulsive or attractive force. What is the separation distance of these charges?

Answer 1

b.

Step-by-step explanation:

Answer 2

Attractive force and r = 0.399 m

Step-by-step explanation:

One charge is positive and the other charge is negative. Opposite charges attract, so there has to be a force that attracts between them.

q1 = 10.0 x 10^-6 C

q2 = -3 x 10^-6 C

F = 1.7 N

Plug those values into Coulomb's Law:

`F = k(q1q2)/(r^(2) ) \\1.7 = ((9x10^(9))(10.0 x 10^(-6))(-3 x 10^(-6)))/(r^(2) )`

Solve for r

r = 0.399 m
