Q. As shown in the figure, two equal masses each of $2\ kg$ are suspended from a spring balance. The reading of the spring balance will be
A) Zero
B) $2\ kg$
C) $4\ kg$
D) Between zero and $2\ kg$
Explanation
(b) In this case, one $2\ kg\ \omega t$ on the left will act as the support for the spring balance. Hence its reading will be $2\ kg$
