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 I2. Please read soilution carefully and feel free to ask any doubt you face while understanding my solution. I would be happy to help.
