Consider a parallel-plate capacitor with charge +q on the top plate and –q on the other, and a plate area that is large
relative to the separation distance. Contrast this with a spherical capacitor consisting of two concentric spherical shells,
one smaller than the other, with a charge of +q uniformly distributed on the outer shell and a charge of –q uniformly
distributed on the inner shell. (a) Do the positive and negative charges distribution contribute equally to the electric eld
inside each capacitor? If not, what fraction of the eld comes from the negative distribution? (b) What is the electric eld magnitude outside each capacitor?

You have been hired to design a spring-launched roller coaster thatwill carry two passengers per car. the car goes up a 10-m highhill, then descends 15m to the track's lowest point. you'vedetermined that the spring can be compressed a maximum o 2.0m andthat a loaded car will have a maximum mass of 400kg. for safetyreasons, the spring constant should be 10% larger than the minimumneeded for the car to just make it over the top. a) what spring constant (k) should you specify ? b) what is the maximum speed of a 350 kg car if the spring iscompressed the full amount.
