Q1. An electron moves through a uniform magnetic field given by =Bx+ (3.00 Bx). At a particular instant, the electron has velocity = (1.26+4.85) m/s and the magnetic force acting on it is (6.79 X 10-19) N. Find out Bx.
Q2. A jetliner with an airspeed of 1000 sets out on a 1300 flight due south. To maintain a southward direction, however, the plane must be pointed 15 west of south. If the flight takes 80, what is the wind velocity?
3. A 100 arrow is shot perpendicularly from a bow whose effective spring constant is 500. If the bow is drawn 75 before shooting the arrow, to what height does arrow rise?
