Q1. A proton moves perpendicular to a uniform magnetic field at a speed of 1.80 x 10^7 m/s and experiences an acceleration of 3.00 x 10^13 m/s2 in the positive x-direction when its velocity is in the positive z-direction. Find out the magnitude and direction of field.
Q2. A long, narrow rectangular loop of wire is moving toward the bottom of page with a speed of 0.025 m/s. The loop is leaving a region in which a 2.1 T magnetic field exists; magnetic field outside this region is zero. All through the time of 1.0 s, what is the magnitude of the change in magnetic flux?
