Two blocks A and B of masses 3m and m respectively are connected by a massless and inextensible string. The whole system is suspended by a massless spring as shown in figure. The magnitudes of acceleration of A and B immediately after the string is cut, are respectively:
As we learnt in
Reaction or Normal Force -
A force which is perpendicular to the surface in contact.
Before cut Kx = 4mg
After cut T=0
