Question

Calculate the electrical force exerted between a 22gram balloon with a charge of -2.6x10^-6c and a wool sweater with a charge of +3.8x10^-6c; the separation distance is .075m

Answer 1

Below

Step-by-step explanation:

Eforce = C q1 q2 / r^2 C = coulomb's constant

= (9 x 10^9) (2.6x 10^-6)(3.8x 10^-6) / (.075)^2 = 15808 x 10^-3

= 15.8 N (attractive force because the forces are opposite charge)
