Consider the mass spectrometer shown schematically in the figure below. The electric field between the plates of the velocity selector is 4900 V/m, and the magnetic fields in both the velocity selector and the deflection chamber have magnitudes of 0.0690 T. Calculate the radius r of the path for a singly charged ion with mass m = 4.29 10-26 kg.
A proton is fired directly into a uniform electric field that is able to bring the charge momen- tarily to rest. How much work does the electric field do in stopping the proton
A race car has a mass of 703 kg. It starts from rest and travels 40.0 m in 3.0 s. The car is uniformly accelerated throughout the entire time. What net force is exerted on it.
A 1 m long pedulum with a 2kg mass is pulled back 0.1m and after that released, so that it swings back and forth. How did they solve T= 2.007 seconds.
A small object is located 31.6{\rm cm} in front of a concave mirror with a radius of curvature of 39.0{\rm cm}. Where will the image be formed
Suppose the mirror is misaligned, so that the actual angle between the normal to the surface and due south is too large by 0.003°. By how many meters (due east) will the reflected ray miss the detector
An aircraft performs a maneuver called an aileron roll. During this maneuver, the plane turns like a screw as it maintains a straight flight path, which is the acceleration of the wing tip
A block is on a rough horizontal surface. A horizontal force of 5N is applied to the block. What is the frictional force exerted on the block
A 92 kg man standing on a surface of negligible friction shoves a 73 g stone lying at his feet, giving it a velocity of 4.0 m/s. What velocity does the man acquire as a result.
A bullet is fired through a board 7.0 cm thick in such a way that the bullet's line of motion is perpendicular to the face of the board, Find the total time the bullet is in contact with the board
A gear system uses 300 joules of energy to move a 20-newton mass 10 meters to the right. How much energy was converted to heat
what is the absolute magnitude of the force on each charge?
An electric dipole has opposite charges of 6.35*10^-15 C seperated by a distance of 0.29mm, Determine magnitude of the torque exerted on the dipole by the electric field.
