Question

C https://www.webassign.net/web/student/Assignment-Responses/submit?depa14530862 Section 18.9 Two tiny conducting spheres are identical and carry charges of -21.6 wc and +4s.5 vo. They are separated by a distance of 2.63 cm. (a) what is the magnitude of the force that each sphere experiences, and is the force attractive or repulsive? N (b) The spheres are brought into contact and then separated to a distance of 2.63 cm. Determine the of the force that each sphere now experiences, and state magnitude hether the force is attractive or repulsive. N Select Additional Materials Section 18.5 My Notes o Ask Tor 22 points I Previous Answers CJ9 18 P 065 conductor is initially electrically neutral, and then a charge +g is placed at the center of the hollow space. Suppose the conductor initially has a net charge of +54 instead eing neutral. what is the total charge on the interior and on the exterior surface when the +q charge is placed at the center? nterior -a

Explanation / Answer

when the spheres are brought in contact , they will have equal charge

q = (q1 + q2 / 2)

= (45.5 - 21.6)/ 2 = 11.95 uC

F = Kq1q2 / r^2

=9*10^9*(11.95*10^-6)^2 / 0.0263^2

= 1858.1 N

the force acting will be repulsive
