Question

1. The spheres are connected by a conducting wire. Find the electrostatic force between the two after equilibrium is reached, where both spheres have the same charge.

what is the magnitude? Two small identical conducting spheres are placed with their centers 0.70 m apart. One is given a charge of 1.2 times 10-8 C, the other a charge of ?2.0 times10-8 C The spheres are connected by a conducting wire. Find the electrostatic force between the two after equilibrium is reached, where both spheres have the same charge.

Explanation / Answer

A) electrostatic force= kq1q2/r^2 (Coulomb's law)

= 1.2*2*9* 10^-16 *10^9/ (0.7*0.7)

=4.4 *10^-6N (attractive force)

b)total charge= -1.2*10^-8C+ 2*10^-8 = 0.8*10^-8 C

force= 0.8 *10^-8 *0.8 *10^-8*9 * 10^9/0.7^2

=1.17*10^-7 N ( repulsive force.. now both the spheres have negative charges)
