Force constant of a spring is K. If one fourth part is detach then force constant of remaining spring will be
The time period of oscillation of a mass suspended by a spring (force constant k) is T. If the spring is cut into three equal pieces, the force constant of each part and the periodic time, if the same mass is suspended from one piece are
A spring of force constant k is cut into two pieces such that one piece is double the length of the other. Then the long piece will have a force constant of :
