A cosmic ray proton moving toward the Earth at 3.80 ✕ 107 m/s experiences a magnetic force of 1.45 ✕ 10−16 N. What is the strength of the magnetic field (in T) if there is a 45° angle between it and the proton's velocity?

Explanation:

The magnetic force is given by the formula

, is the proton charge

the amount of current in the coil

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
