Help! 3 well separted conductin spheres...
three well separated conducting spheres of radii 2.5,4cm, and 6.5cm are charged to .04uC, 0.55 uC and 0.3 uC respectively.
a) Calculate the voltage at the surface of each sphere(assume a zero voltage at infinity) hint: outside the surface, charged spheres behave like pt charges.
b)now assume all three spheres are connected by wires. Calculate the new charges on each sphere
hint: continuous metallic surface are equipotential surfaces.
Thats the problem I have to solve
my soultion so far
a)v=kq/r
for sphere 1: V=(8.99x10*9)(0.4uC)/(.025m)=1.43x10*11
For Sphere 2: V=(8.99x10*9)(.55uC)/(.04m)=1.23x10*11
For Sphere 2: V=(8.99x10*9)(.3uC)/(.065m)=4.15x10*9
b)for all use the formula q/r?
