The blocks of mass `4 kg` and `6 kg`, are attached by spring as shown in figure. Now lower spring breaks due to excessive force. Acceleration of `4 kg` block just after breaking is :

A

`15 m//s^(2)`

B

`25 m//s^(2)`

C

`10 m//s^(2)`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
A
Spring force in upper
spring does not change
intantly at the moment the lower spring breaks.
`a = (10g - 4g)/(4)`
