Two very large parallel plates are oppositely and uniformly charged. The field between the plates is 1.7×106N/C .
How dense is the charge on each plate (in ?C/m2)?
How much total charge is on each plate if they are 18.0cm on a side?
How much work would be required to move a 0.50 microCoulomb test charge from a point midway between them to a point 12 cm closer to ether of the charges?
For many years Colonel John P. Stapp, USAF, held the world's land speed record. He participated in studying whether a jet pilot could survive emergency ejection.
An electron moves in the positive x-direction a distance of 2.31 m in 2.85·10-8 s, bounces off a moving proton, and then moves in the opposite direction a distance of 1.53 m in 3.33·10-8 s.
State the amplitude of the electric field vector in micro volts per meter to three significant figures.
An occupant of a car has a chance of surviving a crash if the deceleration all through the crash is not more than 30.00 g. Approximation the force on a 72 kg person decelerating at this rate.
A 5 kg box block is pushed 3 m up a vertical wall with constant speed by a constant force of magnitude F at an angle of 60 degrees with the horizontal.
A 5,000 kg satellite is orbiting the Earth in a circular path. The height of the satellite above the surface of the Earth is 800km. The velocity of the satellite is (Me = 5.98 x 10^24 kg, Re = 6.37 x 10^6 m, G = 6.67 x 10-11 N • m2/kg2)
A parallel-plate capacitor has an area of 5.15 cm2, and the plates are separated by 1.05 mm with air between them. It stores a charge of 337pC. What is the potential difference across plates of the capacitor.
An airplane is flying with a velocity of 81.6 m/s at an angle of 18.0 above the horizontal. When the plane is the distance 123 m directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from t..
A horizontal board weighing 198 N is supported at points A and B. The plank serves as a platform for a painter, who weighs 558.5 N. Find out the maximum distance D, such that the plank would not tip, no matter where the painter stands.
The potential at location A is 376V. A positively charged particle is released there from rest and arrives at location B with a speed vB.
Then find the force between them as a function of distance h. describe why the sign of the force does (or does not) make sense to you.
