A negative charge − Q is placed inside the cavity of a hollow metal solid. The outside of the solid is grounded by connecting a conducting wire between it and the earth. Is any excess charge induced on the inner surface of the metal? Is there any excess charge on the outside surface of the metal? Why or why not? Would someone outside the solid measure an electric field due to the charge − Q ? Is it reasonable to say that the grounded conductor has shielded the region outside the conductor from the effects of the charge − Q ? In principle, could the same thing be done for gravity? Why or why not?

1. What is the spring constant of a spring that starts 10.0 cm long and extends to 11.4 cm with a 300 g mass hanging from it?
please help me solve all parts of this question from physics. thanks so much in advance! :)))
A fluid with density 263 kg/m3 flows through a pipe of varying diameter and height. At location 1 the flow speed is 13.5 m/s and the diameter of the pipe is 7.4 cm down to location 2 the pipe diameter is 16.9 cm. Location 1 is 6.3 meters higher than location 2.
What is the difference in pressure P2 - P1?
Using units in Pascals and use g = 9.81 m/s2.
