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.

A

`F_(c.p)= kx_(0)`

B

`F_(c.p)= (mv^(2))/(l_(0)+x_(0))`

C

`F_(c.p) = kx_(0)- (mv^(2))/(l_(0)+x_(0))`

D

A block of mass m is connected to another block of mass M by a spring (massless) of spring constant k. The blocks are kept on a smooth horizontal plane. Initially the blocks are at rest and the spring is unstretched. Then a constant force F starts acting on the block of mass M to pull it. Find the force on the block of mass m

A body of mass m is tied to one end of a spring and whirled round in a horizontal plane with a constant angular velocity and elongation in the spring is 1 cm. If the angular velocity is doubled, the elongation in the spring becomes 5 cm. The original length of spring is
