If a proton is moving perpendicular to a uniform magnetic field, it will experience a magnetic force that will pull the proton out of its straight- line path and cause it to travel in a circle of radius r. Find the magnitude of the magnetic force for a proton moving at 3x10 m/s perpendicular to a magnetic field of 1.5 T.​

The extremely high temperatures needed to trigger nuclear fusion are proposed to be generated by laser irradiating a spherical pellet of deuterium and tritium fuel of diameter 1.8 mm. (a) determine the maximum fuel temperature that can be achieved by irradiating the pellet with 200 lasers, each producing a power of 550 w. the pellet has an absorptivity 0.3 and emissivity 0.8.
