In a color TV picture tube, an electric field exerts a net force with magnitude 1.60 x 10-13 N on an elec- tron (m = 9.11 x 10-34 kg). What is the electron's acceleration? Suppose the mass of the chain in Example 4.7 is not negligible. but is 10.0 kg. Find the forces at the ends of the chain. You stand on a bathroom scale that rests on the floor of an elevator. (Don't ask why!) Standing on the scale compresses internal springs and activates a dial that indicates your weight in newtons. When the elevator is at rest, the scale reads 600 N. Then the elevator begins to move upward with a constant acceleration a, - 2.00 m/s2. (a) Determine your mass. (b) Determine the scale reading while the elevator is accelerat- ing. (c) If you read the scale without realizing that the elevator is accelerating upward. what might you think your mass is?
