1.	A particle of mass 'm' attached with one end of a light spring of stiffness (k) is pushed with a speed (v) on a smooth horizontal plane. If l_(0)= natural length of the spring and x_(0) = elongation of the spring at the given instant.
Answer» `F_(c.p)= kx_(0)` `F_(c.p)= (mv^(2))/(l_(0)+x_(0))` `F_(c.p) = kx_(0)- (mv^(2))/(l_(0)+x_(0))` All of the above Answer :A
