A particle with a charge of -60.0 nC is placed at the center of a nonconducting spherical shell of inner radius 20.0 cm and outer radius 23.0 cm. The spherical shell carries charge with a uniform density of -2.35 µC/m3. A proton moves in a circular orbit just outside the spherical shell. Calculate the speed of the proton.
A 2,200-kg car moving east at 10.0 m/s collides with a 3,000-kg car moving north. The cars stick together and move as a unit after the collision, Find the speed of the 3,000-kg car before the collision
The potiential energy of a + 2 * 10^-6 C charge decreases from 0.06J to 0.02J, What is the change in electric potiental between these two points
An atomic nucleus of mass m traveling with speed v collides elastically with a target particle of mass 2m initially at rest and is scattered an 90 degrees. what angle does the target particle move after collision
An RL circuit consists of a switch, an emf source Eo, a 4 kΩ resistor, and a 5 H inductor. If the potential across resistor is 16 V 5 ms after switch is closed, find out the source emf, Eo.
Determine the angular speed of a speck of dirt located 1.97 cm from the center of a CD rotating inside a CD player at 263 rpm.
When a battery is connected to a 100-? resistor, the current is 4.00 A. When the same battery is connected to a 442-? resistor, Find the emf supplied by the battery
A constant voltage of5.00 V has been observed over a certain time interval across a 3.00H inductor. How long was this time interval
Consider a grounded conducting sphere of radius "a" in the presence of a point charge "Q" a distance "D" away from the center of the sphere. How do you show the electric field E is everywhere normal of the sphere, and how do you find the induced char..
a uniform electric field of magnitude 200 vm is directed in the negative x direction. a 10.7 muc charge moves from the
The energy released by nuclear bombs is measured in kiloton (kt) or megaton (Mt) units. One kiloton is a unit of energy released by 1000 tons of trinitrotoluene (TNT). One kiloton is 4.2×1012 joules. The yield of fission bombs is typically between..
