1.	What is the effect on (i) the force constant of the spring (ii) the frequency of oscillations? If the amplitude of oscillations of a loaded spring is doubled.
Answer» SOLUTION :When amplitude of a loaded spring is doubled then there is no change in the VALUE of force CONSTANT of the spring. (i) Force constant K `=("Force")/("displacement")`. (ii) Time period of a loaded spring `T= 2pi (m/k)` . It is independent of amplitude of oscillation.
