A charged particle moving in the presence of a 0.750 T magneticfield experiences a magnetic force of magnitude 2.50 * 10^-10 N.The particle is moving at 1.95 * 10^5 m/s at an angle of 36.0° to thedirection of the magnetic field. Find the magnitude of the charge on theparticle.

A proton travels with a speed of (5.3x10^4) m/s along the x-axis. A uniform magnetic field of strength (9.200x10^-4) T directed along the y-axis is turned on, and the proton starts travelling in a circle due to the magnetic force. What is the radius of this circle? Give your answer in meters (m) using scientific notation.

A charge is moving perpendicular to a magnetic field and experiences a force whose magnitude is 2.15 × 10-3 N. If this same charge were to move at the same speed and the angle between its velocity and the same magnetic field were 26.0o, what would be the magnitude of the magnetic force that the charge would experience?

As shown in the figure below, when a charged particle enters a region of magnetic field traveling in a direction perpendicular to the field, it will travel in a circular path. If the magnitude of the magnetic field is 0.190 T, the speed of the particle is 12.0 x 106 m/s, the radius of the trajectory of the path is 104.7 cm, and the charge has a magnitude of 3.20 x 1019 C, determine the following. (a) sign of the charged particle O positive O negative (b) mass of the particle (Use the conversion 1 u = 1.66 x 1027 kg.)
