1. A cosmic ray proton moving toward the Earth at 5.5 × 107 m/s experiences a magnetic force of 1.65 × 10-16 N .

What is the strength of the magnetic field if there is a 45º angle between it and the proton’s velocity?

2. A 2.25 m segment of wire supplying current to the motor of a submerged submarine carries 950 A and feels a 3.9 N repulsive force from a parallel wire 5.00 cm away.

What is the magnitude of the current in the other wire in A?

Expert Solution

Solution :-

Solution to these problems are based on the concept of force on a moving charge in magnetic field and force on a current carrying wire in magnetic field. Force(F) on a moving charge(q) moving with velocity v in magnetic field (B) is given as : and force(F) on a current(I) carrying wire of length L in magnetic field(B) can be given as : , in question 2, B is magnetic field created by current(I₁) and force is experienced due to this field on I_2. Please read soilution carefully and feel free to ask any doubt you face while understanding my solution. I would be happy to help.
