Answer to Question #299342 in Electric Circuits for HYEHYE

Question

One charge of 2C is 1.5meters away from a -3C charge. Determine the force exerted on each other.

 

A -6 micro coulomb charge exerts an attractive force of 65N on a second charge that is 5cm away.What is the magnitude of the second charge?

Answer 1

Solution;

(a)

$F=\frac{kq_1q_2}{r^2}$

$F=\frac{8.99×10^9×2×3}{1.5^2}=2.397×10^{10}N$

(b)

$65=\frac{8.99×10^9×6×10^{-6}×q_2}{0.05^2}$

$q_2=3.01\mu N$
