An electron moves at 2.50 X 10^6 m/s through a region in which there is a magnetic field of unspecified direction and magnitude 7.40 X 10^-2 T. (a) what are the largest and smallest possible magnitudes of the velocity of the electron due to the magnetic field? (b) if the actual acceleration of the electron is one-fourth of the largest magnitude in part (a), what is the angle between the electron velocity and the magnetic field?
An electron experiences a magnetic force of magnitude 4.60 X 10^-15 N when moving at an angle of 60.0 with respect to a magnetic field of magnitude 3.50 X 10^-3 T. Find the speed of electron
triply ionized particles in a beam carry a net positive charge of 3 elementary charge units, the beam enters a magnetic field of 4.0*10^-2T the particles have a speed of 9.0*10^6m/s
Three charges 2q, 4q and 2q are to be placed on a 1.0 m long straight wire.
Determine the positions where the charges should to be placed so that the potential
energy of the system is a minimum.
A uniform electric field is directed along the x-axis between the parallel plated of a charged capacitor, separated by a distance. A positive point charge of mass is released from rest at point A next to the positive plate and accelerates to point B next to the negative plat.
Find the speed of the particle at point B if the motion is under constant acceleration.
Three charges were present inside the coil. The charges were labeled “a”, “b”, and “c”. Charge “a” has a value of 20µc, charge “b” has a value of -50µc and charge “c” has a value of 15µc. Each charge has a distance of 5m to each other.
