Two block of mass 4 kg and 5 kg attached...

Two block of mass 4 kg and 5 kg attached a light spring are suspended by a string as shown in figure. Find acceleration of block 5 kg and 4 kg just after the string is cut.

A

`8 m//s^(2), 10 m//s^(2)`

B

`10 m//s^(2), 10 m//s^(2)`

C

`18 m//s^(2), 0`

D

`8 m//s^(2), 0`

Text Solution

Verified by Experts

The correct Answer is:
C
When string is cut tension in string becomes zero. But spring doesn’t change its shape just after cutting the string
kx = 40 N
So force due to spring on both
Blocks remains same
