1. A conducting sphere with a radius of 0.15 m has a charge of 10 pC. a. What is the potential at the surface of the sphere? b. A particle of charge 1.0 µC and mass 2.0 x $10^{-7}$ kg is released from rest from the surface of the sphere. How fast is it moving when it reaches a distance of 0.6 m from the center of the sphere? (you may neglect gravity) c. Now the sphere is connected by a long wire with a resistance of 5.0 $\Omega$ to a second sphere. The second sphere has a radius of 0.30 m and also has a charge of 10 pC. Immediately after the wire gets connected, what current flows through it? d. As time passes does this current increase, decrease, or stay constant? Explain. e. After a long time has passed, what is the charge on the first sphere?
