When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the sky diver and, thus, slows him down. Suppose the weight of the sky diver is 852 N and the drag force has a magnitude of 1018 N. The mass of the sky diver is 86.9 kg. Take upward to be the positive direction. What is his acceleration, including sign?
A uniform magnetic field exerts a force on a moving charge which is equal to the...
A uniform magnetic field exerts a force on a moving charge which is equal to the charge times the vector product of the velocity and the magnetic field. Can this force change the magnitude of the velocity of the charge? Explain. Can both uniform electric and magnetic fields exist (for non-zero fields) where the net force on a charge is zero? If so, what are the constraints on the fields? If not, why not?
