Two blocks A and B of same mass m attached with a light spring are suspended by a string as shown in fig. Find the acceleration of block A and B just after the string is cut.

Consider a system of two massless idealsprings and a block which is in equilibrium. The acceleration of block just after cutting the right spring is (Take g = 10 m//s^(2) ):

A block is attached with an ideal spring and string, and is in equilibrkum as shown in Figure. The acceleration of the block just after breaking the string is a_(1) and just after breaking the spring is a_(2) . Then

A block tied between identical springs is in equilirium. If upper spring is cut, then the acceleration of the nlock just after cut is 5 ms^(1) Now if instead of upper string lower spring is cut, then the acceleration of the block just after the cut will be (Take g=10 m//s^(2) ).
