Question
A sphere of mass m is kept in equilibrium with the help of several springs as shown in the figure. Measurement show that one of the spring applies a force
on the sphere. with what acceleration the sphere will move immediately after this particular spring is cut ?


Options
A.Zero
B.
/ m
C.-
/ m
D.insufficient information
Solution
let forces acting on mass m in equilibrium are 
[equilibrium condition]
⇒
......(i)
After cutting the string with force
, the net force on mass m
[(From (i))]
⇒
After cutting the string with force
