Question

two blocks A and B of masses 2m and M are connected as shown in figure the spring has negligible mass the string is suddenly cut the magnitude of acceleration of masses to 2m and m at that instant are the ​

Answer 1

Answer:

g/2 and g

Explanation:

Two blocks A and B of mass 2mand m respectively and they are connected by a mass less and in extensible string.

The equilibrium condition FBD of 2m

Kx=T+2mg

=mg+2mg=3mg

After the string is cut

T=0

FBD of 2m

a2​=2m3mg−2mg​=2g​

FBD of m

Hence 2g​ and g
