Two spherical shells have a common center. A -3.00 × 10-6 C charge is spread uniformly over the inner shell, which has a radius of 0.050 m. A +4.00 × 10-6 C charge is spread uniformly over the outer shell, which has a radius of 0.15 m. Find the magnitude and direct...

*update i found the speed. it was 23.5 m/s so with this i could find #1,2 and 3. But I still need help with #4 and 5!

Sorry, still confused. I get that the density for mercury is 13.6x10^3 kg/m^3. All I know is that the answer is 4.08m, I just don't know how to get there. Do I use P=density*gravity*height h=pressure/density*9.8 but my answer didn't even come close to 4m

Oops! I forgot that it was a 2 part question. Part 1: Calculate the bouyant force on a 2.00 L helium balloon. Volume:2.00 L Helium's density: 0.18x10^-3 FB=density*gravity*volume=> 3.53x10-3 N other then these numbers nothing else was given for part 2(the part i need he...
