What is e(r), the radial component of the electric field between the rod and cylindrical shell as a function of the distance r from the axis of the cylindrical rod? express your answer in terms of λ, r, and ϵ0, the permittivity of free space. view available hint(s) e(r) e r e(r) = nothing part b what is σinner, the surface charge density (charge per unit area) on the inner surface of the conducting shell? view available hint(s) σinner σ i n n e r sigma_inner = nothing part c what is σouter, the surface charge density on the outside of the conducting shell? (recall from the problem statement that the conducting shell has a total charge per unit length given by −2λ.) view available hint(s) σouter σ o u t e r sigma_outer = nothing part d what is the radial component of the electric field, e(r), outside the shell?

Aparticle of mass m is projected with an initial velocity v0 in a direction making an angle α with the horizontal level ground as shown in the figure. the motion of the particle occurs under a uniform gravitational field g pointing downward. (a) write down the lagrangian of the system by using the cartesian coordinates (x, y). (b) is there any cyclic coordinate(s). if so, interpret it (them) physically. (c) find the euler-lagrange equations. find at least one constant of motion. (d) solve the differential equation in part (c) and obtain x and y coordinates of the projectile as a function of time. (e) construct the hamiltonian of the system, h, and write down the hamilton’s equations (canonical equations) of motion.

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
