Consider a system of two massless idealsprings and a block which is in equilibrium. The acceleration of block just after cutting the right spring is (Take `g = 10 m//s^(2)` ):

Options

A. `5 m//s^(2)`
B. `10 m//s^(2)`
C. `10 sqrt2 m//s^(2)`
D. `20 m//s^(2)`

Answer

B

Explanation

After cutting

`F_("net") = 5 g`
`a = (F_("net"))/(m) = g`
