Problem #1: Electrostatics - Conducting Surface Given two spherical conductors (metals) placed in close proximity as shown below: 1201 29-59 Assume that these spheres are brought into contact momentarily and then separated away. Compute the followings: (i) Net charge present in both spheres, (ii) Effective charge present on individual spheres respectively.

Answer 1

(ii) Charge transter happens when both sphere are touched Charge on each = Ines a net = 150

ie posential (11) charse enfare Charse transfer happens untill v=v₂ at surface of bom sphers are equal - a final charge on big sple V2 final charge on small spher an final chanx on small splen 9 ka = ke . a = 2 Q2 - (i) Q, + 9 = 150 - i) we know solving bom we get (a = 100 (22= 50)
