A small conducting spherical shell with inner radius a and outer radius b is concentric with a larger conducting spherical shell with inner radius c and outer radius d (see the Figure (Figure 1) ). The inner shell has total charge +2q, and the outer shell has charge +4q.
A) Calculate the magnitude of the electric field in terms of q and the distance r from the common center of the two shells for r B) Calculate the magnitude of the electric field in terms of q and the distance r from the common center of the two shells for a C) Calculate the magnitude of the electric field in terms of q and the distance r from the common center of the two shells for b D) Calculate the magnitude of the electric field in terms of q and the distance r from the common center of the two shells for c E) Calculate the magnitude of the electric field in terms of q and the distance r from the common center of the two shells for r>d. Express your answer in terms of the variables q, r, a, b, c, d, and constants ? and ?0.

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
