A uniform electric field exists in the region between two oppositely charged parallel plates 1.67cm apart. A proton is released from rest at the surface of the positively charged plate and strikes the surface of the opposite plate in a time interval 1.53×10?6s .
part A: Find the magnitude of the electric field. Use 1.60×10?19C for the magnitude of the charge on an electron and 1.67×10?27kg for the mass of a proton.
Part B: Find the speed of the proton at the moment it strikes the negatively charged plate.
The threshold of dark-adapted (scotopic) vision is 6 multiplied by 10-11 W/m2 at a central wavelength of 550 nm. If light with this intensity and wavelength enters the eye when the pupil is open to its maximum diameter of 7.5mm, how many photons p..
What is sign and magnitude of charge
The ramp is slanted at an angle of 17.0 degrees to the horizontal. Illustrate what is the coefficient of kinetic friction between the block and the ramp?
Consider an angular motion. If the displacement is given as 250teθ, and the radius r is constant, derive the expressions for the angular velocity θ=ω, angular accelerationα, linear displacements, linear velocitytv, normal accelerationna, and tange..
Although both stars probably formed from the same clump of gas, more massive one must have had its birth slowed so that it became a key -sequence star millions of years later than its less massive companion.
A point charge with charge q1 is held stationary at the origin. A second point charge q2 with charge moves from the point (x1, 0) to the point (x2,y2 ). How much work is done by the electrostatic force on the moving point charge? Express your answ..
A 100 ball on a 60 long string is swung in a vertical circle whose center is 200 above the floor. The string suddenly breaks when it is parallel to the ground and the ball is moving upward. The ball reaches a height 600 above the floor.What is the..
With two fingers, you hold an ice cream cone motionless upside down the mass of the cone is m, and the coefficient of static friction between your fingers and the cone is? When viewed from the side, the angle of the tip is 2?
A shop sign weighing 245-N is supported by a uniform 155-N bean. Find out the tension in the guy wire, and the horizontal and vertical forces exerted by the hinge on the bean.
The frequency doubled output of a Nd3+ YAG laser has a wavelength of 532nm. If each pulse of light has a total energy of 0.550J and the repetition rate of the laser is 30Hz, how many photons does the laser emit at 532nm in 3 minutes?
In the Millikan oil-drop experiment, an atomizer (a sprayer with a fine nozzle) is used to introduce many tiny droplets of oil between two oppositely charged parallel metal plates.
A 8.9 dog takes a nap in a canoe and wakes up to find the canoe has drifted out onto the lake but now is stationary. He walks along the length of the canoe at 0.54, relative to the water, and the canoe simultaneously moves in the opposite direction a..
