A block of mass $m$ is attached to two springs of spring constants $k_1$ and $k_2$ as shown in figure. The block is displaced by $x$ towards right and released. The velocity of the block when it is at $x/2$ will be

A

$\sqrt {\frac{{\left( {{k_1} + {k_2}} \right){x^2}}}{{2m}}} $

B

$\sqrt {\frac{3}{4}\frac{{\left( {{k_1} + {k_2}} \right){x^2}}}{m}} $

C

$\sqrt {\frac{{\left( {{k_1} + {k_2}} \right){x^2}}}{m}} $

D

$\sqrt {\frac{{\left( {{k_1} + {k_2}} \right){x^2}}}{4m}} $
