Alpha particles(charge q =+2e, mass m = 6.6×10−27kg move at 1.7×106 m/sWhat magnetic field strength would be required to bend them into a circular path of radius r = 0.13 m ?

(a) An oxygen-16 ion with a mass of 2.66 × 10−26 kg travels at 5.0 × 106m/s perpendicular to a 1.20-T magnetic field, which makes it move in a circular arc with a 0.231-m radius. What positive charge is on the ion? (b) What is the ratio of this charge to the charge of an electron? (c) Discuss why the ratio found in (b) should be an integer.

When a proton has a velocity of (2i+8j)*10^6 m/s , it experiences a force of -1.6*10^-13k N. . In a second experiment with the same B field, the particle is moving along the + z-axis and under these new conditions it experiences a force along the + x-axis . What is the magnetic field? answer should be in (i,j,k)

Alpha particles (mass = 6.7 × 10^-27 kg, q = +2e) are accelerated from rest through a potential difference of 3.0 kV. They then enter a uniform magnetic field B = 0.40 T perpendicular to their direction of motion. Calculate the radius of their path. Problem in photo.

An alpha particle with velocity v = (3 x 105,0,0) m/s enters a region where the magnetic field has a value B = (0,0,1.2) T. Determine the required magnitude and direction of an electric field E that will allow the alpha particle to continue to move along the x axis.

Atom 1 of mass 35 u and atom 2 of mass 37 u are both singly ionized with a charge of +e. After being introduced into a mass spectrometer (see the figure below) and accelerated from rest through a potential difference V = 7.5 kV, each ion follows a circular path in a uniform magnetic field of magnitude B = 0.30 T. What is Δx, the distance between the points where the ions strike the detector?
