Conductor Surface Charge#

The conductor in the figure has an excess charge of $${{params.Q}}\rm\ \mu C$$. A point charge $$q = {{params.q}}\rm\ \mu C$$ is placed in the cavity.

Part 1#

What is the net charge on the surface of the cavity? Give your answer in units of micro-Coulombs.

Part 2#

What is the net charge on the outer surface of the conductor? Give your answer in units of micro-Coulombs.

$$Q\_\mathrm{cavity}=$$ $$\rm\ \mu C$$
$$Q\_\mathrm{outer}=$$ $$\rm\ \mu C$$
