Acosmic ray proton moving toward the earth at 3.5x 10^7 ms experiences a magnetic force of 1.65x 10^-16 n. what is the strength of the magnetic field if there is a 45° angle between it and the proton's velocity?

Magnetic field,

Explanation:

It is given that,

Velocity of proton,

Magnetic force,

Charge of proton,

We need to find the strength of the magnetic field if there is a 45° angle between it and the proton's velocity. The formula for magnetic force is given by :

B = 0.0000416 T

Hence, this is the required solution.
