Asimple pendulum consists of a point mass suspended by a weightless, rigid wire in a uniform gravitation field. which of the following statements are true when the system undergoes small oscillations? check all that apply.
the period is inversely proportional to the suspended mass. the period is proportional to the square root of the length of the wire. the period is independent of the suspended mass. the period is proportional to the suspended mass. the period is independent of the length of the wire. the period is inversely proportional to the length of the wire.

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
