As shown in the following figures, block of mass 2 kg is in equilibrium in the vertical plane.
At a certain instant right spring in case-1 and right string in case-2 are cut. Then the ratio of
instantaneous acceleration of block in case-1 to case-2 just after the cutting is
(strings and springs are ideal)
A
0
B
l
C
D
none of these
Text Solution
Verified by ExpertsThe correct answer is:
C
Now when spring is cut in case-1 then net force F 1 acting on block is,
(resultant force of the remaining T = 
N and mg = 20
N forces)
Similarly, when the string is cut in case-2 then net force F 2 acting on block is
