A particle of mass m = 2kg executes SHM in xy plane between points A and B under the action of force Image not present = Fxî + Fyĵ. Minimum time taken by the particle to move from A to B is 1s. At t = 0 the particle is at x = 2 and y = 2. Then Fx as function of time is :-
a) -4pi2sinpit
b) -4pi2cospit
c) 4pi2cospit
d) None
