A cosmic ray proton moving toward the Earth at 5.00x10' m/s experiences a magnetic force of 1.70x1016 N. What is the strength of the magnetic field if there is a 45° angle between it and the proton's velocity? (b) Is the value obtained in part (a) consistent with the known strength of the Earth's magnetic field on its surface?

Could you please answer number 2. Thank you.

1. The figure below shows the resistors -a combination of series and parallel. We can consider R1 to be the resistance of wires leading to R2 and R3. (a) Find the total resistance. (b) What is the IR drop in R1? (c) Find the current 12 through R2. (d) What power is dissipated by R2 ? V, = ? 1.00 2 R, 1= ? ½ = ? 12.0 V R 6.00 2 13.0 2 2. A cosmic ray proton moving toward the Earth at 5.00x107 m/s experiences a magnetic force of 1.70×1016N. What is the strength of the magnetic field if there is a 45° angle between it and the proton's velocity? (b) Is the value obtained in part (a) consistent with the known strength of the Earth's magnetic field on its surface?
