1.	A force given by: F = -2(x – 1)^2acts on a particle at rest. Select the correct option regarding the same.(a) Force acts on particle along the positive x direction(b) Force is never zero(c) Motion is periodic but not oscillatory(d) Motion is rectilinearThis question was posed to me in an interview.I would like to ask this question from Periodic and Oscillatory Motions in division Oscillations of Physics – Class 11
Answer» Right CHOICE is (d) MOTION is RECTILINEAR For explanation: Force always acts in the negative direction, so motion is not PERIODIC. Motion is rectilinear since the particle will always travel in a straight line. Force is zero at x=1.
