Question

+7.6uC charge with mass of 0.13mg is placed 2.54m above
-3.61uC/m^{2} disk of charge with diameter of 0.1m. How
fast will charge be going when it falls to 0.83m above the
disk?

Answer #1

A disk of diameter 80.0cm and mass 50.0g is free to rotate about
its center and initially at rest. A lab mouse of mass 30.0g is
carefully placed on the edge of the disk at rest. The mouse starts
running around at the edge of the disk at a speed of 20.0cm/s
relative to the ground. 1) How fast, in rpm, is the disk rotating
now? 2) What is the total kinetic energy of the system?

Consider the classic image problem with a point charge q placed
a distance d above a grounded conducting plane. The charge, which
has mass m, is released from rest. How fast will it be moving when
it is half as far away from the plane (d/2)?

A disk with a mass is 3kg. diameter is 20cm, rotating about its
symmetry axis
a) compute the rational inertia of the disk
b)three 1 kg masses are placed at the edge of this disk, each
seperated by 120 degrees. what is the total rotaional
inerteria?

A disk of diameter d1 rests on a table. A
second disk of diameter d2 is placed with its
rim touching the rim of the first disk. See the figure below. You
hold the inner disk down so it does not move, and you roll the
outer disk around the circumference of the first one, making sure
that there is no slipping of the disk. If
d1 = 2d2,
how many revolutions does it make in one round trip?

A pully disk 4 meters in diameter with a mass of 5 kg has a mass
hanging from either side exerting a 20 N and 30 N respectively.
1.What minimum static torque exerted by friction at the axle
will keep the system at rest?
The kinetic torque, the torque on the axle when the system is in
motion, is half of the static value.
2.Once in motion, what is the angular acceleration of the pulley
disk?

A uniform solid disk of mass 3.60 kg and diameter 45.0 cm starts
from rest and rolls without slipping down a 39.0 ? incline that is
6.25 m long. g = 9.81 m/s2 .
(a) Calculate the linear speed of the center of the disk when it
reaches the bottom of the incline.
b) Determine the angular speed of the disk about its center at
the bottom of the incline.
c) Through what angle (in radians) does this disk turn as...

A point charge of -3.5 micro-coulombs with a mass of 0.42 kg is
placed in a uniform electric field directed in the +x direction.
Initially, the charge is moving in +x direction at 9.5 m/s and
after it has traveled a displacement of 2.2 meters in the -x
direction, it is moving at 24.7 m/s in the -x direction. If a piece
of paper with an area of 0.5 m2 is placed in the field and the
angle between the...

In a hole meter a flat disk with a central diameter opening is
placed transversely to a pipe of diameter D, and the pressure drop
??? is measured through the opening. It is postulated that ??? is a
function of the average velocity of the fluid in pipe V, the
density of the flow ?, the viscosity of the fluid ? and the
parameters of the pipe and the opening. D and Do, respectively. In
this way
?p= ? (V,?,?,D,Do)...
