Homework Answers
Increasing the density will increase the mass of sphere. This will make an effect on kinetic energy. Kinetic energy increases. Remaining all parameters are independent of mass. Hence they remain Same.
Hence option 4 is correct .

(a) Consider a pendulum with a mass m suspended at the end of a light string of length l. As it moves through the air the mass experiences a damping force that is proportional to its speed, with constant of proportionality y. (i) Show that the angle θ that the string makes with the vertical is governed by the ordinary differential equation dt2 m dt l in the limit of small θ. 1) State the natural frequency wo of the...

Consider a simple pendulum consisting of a massive bob suspended from a fixed point by a string. Let T denote the time (period of the pendulum) that it takes the bob to complete one cycle of oscillation. How does the period of the simple pendulum depend on the quantities that define the pendulum and the quantities that determine the motion? [You need to perform a dimensional analysis to solve this one. Start by assuming T = k Inmpgq, where k...

A charged sphere is suspended from a string in a uniform electric field directed horizontally. There is an electric force on the sphere to the right and a gravitational force pointing downward. As a result, the sphere hangs at an angle theta from the vertical. Combinations of sphere mass and electric charge are listed in the chart for four cases, all in the same uniform electric field. Rank the angle theta that the string forms with the vertical for these...
