The two masses `m_(1)` and `m_(2)` are joined by a spring as shown. The system is dropped to the ground from a height. The spring will be

Options

A. Streched when `m_(2)gtm_(1)`
B. Compressed when `m_(2)ltm_(1)`
C. neither compressed not stretched only when `m_(1)=m_(2)`
D. neither compressed not stretched regardless of the values of `m_(1)` and `m_(2)`.

Answer

D

Explanation

The system, as a whole, will fall towards ground under gravity. The spring will neither be compressed nor stretched regradiess of the values of `m_(1)` and `m_(2)`.
