Question

The string between blocks of mass m and 2m is massless and inextensible. The system is suspended by a massless spring as shown. If the string is cut find the magnitudes of accelerations of mass 2m and m (immediately after cutting)

A. `g,g`
B. `g ,(g)/(2)`
C. `(g)/(2),g`
D. `(g)/(2),(g)/(2)`

Answer 1

Correct Answer - C
For `m_(1), F =ma =m_(1) g,` for `m_(2),T -m_(2)g =m_(2) a^(1)` .
