A spherical conductor with radius 2.00 cm is centered on the origin and holds charge q1=-250 nC. It is surrounded by a concentric spherical conducting shell with net charge q2=+100nC. The conducting shell has inner radius 8.00 cm and outer radius 10.0 cm. The changes are in electrostatic equilibrium.
a) Find the electric flux through a spherical Gaussian surface with radius 15.0 cm, centered on the origin.
b) Find the surface charge density a(charge per area) on the outside surface of the outer spherical shell.
A 1000 kg aircraft going 25 m/s collides with a 1500 kg aircraft that is parked and they stick together after the collision and are going 10 m/s after the collision
Consider two closely spaced and oppositely charged parallel metal plates. The plates are square with sides of length L and carry charges Q and -Q on their facing surfaces. What is the magnitude of the electric field in the region between the plate..
Consider a string with length 36 cm. The two ends are attached to the ceiling, separated by distance 30.0 cm. A 1 kg mass is attached to the string at distance 15 cm from the left end. Then the mass hangs suspended in Earth's gravity. (a) Determin..
A highly charged piece of metal (with uniform potential throughout) tends to spark at places where the radius of curvature is small, For that amount of charge, what is the potential of the sphere relative to infinity
The coefficient of static friction between the 3000 lb car's tires and the road is 0.5. Determine the steepest grade the car can drive up at constant speed if car has (a) rear=wheel drive; (b) front-wheel drive; (c) four wheel drive.
The radar system at an airport broadcasts 11 microwaves with 150 of power. An approaching airplane with a 31 cross section is 24 away. suppose that the radar broadcasts uniformly in all directions and that the airplane scatters microwaves uniformly..
Two speakers, 6.00 m apart, are driven by the same audio oscillator so that each one produces a sound consisting of two distinct frequencies, 1000 Hz and 1360 Hz. The speed of sound in the room is 350 m/s.
A heat engine having an ideal monatomic gas as a working substance has a cycle consisting of the following three processes: isobaric expansion at 200 kPa.
Unpolarized light travels throughout 2 linear polarizers. What (minimum) angle should the second polarizer be relative to the first polarizer (the difference between q1 and q2) so that the final intensity of light is 1/3 original value.
What is the maximum height, y2, if the object is thrown with a speed of v2 = 1.99v1 from the surface of Jupiter's moon Io? The acceleration due to gravity on Io is g2 = 1.79 m/s2. Give the reply as a multiple of y1.
Find the surface tension force on water inside a tube and height to which the water rises in the tube.
You can think of the work?kinetic energy theorem as a second theory of motion, parallel to Newton's laws in describing how outside influences affect the motion of an object. Use the work-kinetic energy theorem to find the net work that is done on t..
