Q1. An electron with a speed of 6.12 × 108 cm/s in the positive direction of an x axis enters the electric field of magnitude 2.70 × 103 N/C, travelling along a field line in the direction that retards its motion. (a) How far would the electron travel in the field before stopping momentarily, and (b) how much time would have elapsed?
Q2. Yusef pushes a chair of mass = 51.0 across a carpeted floor with a force (the subscript 'p' here is lowercase and throughout the question) of magnitude = 170 directed at = 35.0 below the horizontal. The magnitude of the frictional force between the carpet and the chair is = 99.8.
