Positive point charges q and 2q are located at x = 0 and x = 3d, respectively. What is the electric field at x = d (point P)? (Use any variable or symbol stated above along with the following as necessary: k for Coulomb constant.) magnitude E = direction
Calculate the electrostatic force exerted on the point charge by the cylinder and what level of uncertainty would be acceptable in the initial position? You may assume that the uncertainty in all other parameters is negligible
What will the force be between these charges. What should the banking angle of the curves be so that the force of the pavement on the tires of the car is in the normal direction.
An archer puts a 0.26 kg arrow to the bowstring. An average force of 213 N is exerted to draw the string back 1.3 m. unless otherwise directed, suppose that air resistance is negligible. Illustrate energy bar graphs to solve the problem.
An infinitely long line of charge has a linear charge density of 5.50×10-12 C/m. A proton is at distance 17.5 cm from the line and is moving directly toward line with speed 2900 m/s.
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)
What should be the spring constant of a spring designed to bring a 1400 car to rest from a speed of 95 so that the occupants undergo a maximum acceleration of 5.
Two runners start simultaneously from the same point on the circular 200 m track and run in opposite directions. One runs at a constant speed of 6.14 m/s and the other runs at a constant speed of 5.43m/s. When they first meet, for how long a time ..
A block of mass 4.0 kg is put on top of a block of mass M = 5.5 kg. To cause the top block to slip on the bottom one, while the bottom one is held fixed, a horizontal force of at least 16 N must be applied to the top block. The assembly of blocks is ..
Two loudspeakers face each other, vibrate in phase and produce identical 416 Hz tones. A listener walks from one speaker toward the other at the constant speed and hears the loudness change.
Clifford is in a real hurry, however, and skips the speed ramp. Starting from rest with an acceleration of 0.49 m/s2, he covers the same distance as the ramp does, but in one-fourth the time. What is the speed at which belt of the ramp is moving.
Coherent light with wavelength 601 passes through two very narrow slits, and interference pattern is observed on a screen a distance of 3.00 from the slits.
Draw a motion diagram for the train. Assume that the train is moving toward the right and starts to slow down at t = 0. The separation of each dot represents an elapsed time of one second.
