The block shown in the figure in is equilibrium. Find acceleration of the block just after the string burns.

A

`(3 g)/(5)`

B

`(4 g)/(5)`

C

`(4 g)/(3)`

D

None

Text Solution

Verified by Experts

The correct Answer is:
C

Before burning
`Kx cos 53^(@) = mg`
`Kx sin 53^(@) = T`
After burning, spring force remains same at the instant

`bar(a) = (vec(F)_("net"))/(mg)`
