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.
A particle oscillates with S.H.M. The maximum displacement from its mean position is 0.5 meter and frequency of motion is 10 Hz. at time t=0, particle is located at 0.15 meter and has the velocity of 24.0 m/s towards the negative x-axis.
