A block of mass m is attached to two unstretched springs of springs constant `k_(1)` and `k_(2)` as shown in figure. The block is displaced towards right through a distance x and is released. Find the speed of the block as it passes through the mean position shown.
A. `(k_(1)+k_(2))/(m)xx`
B. `(k_(1)k_(2))/(m(k_(1)+k_(2)))xx`
C. `sqrt((k_(1)^(2)k_(2)^(2))/(m(k_(1)+k_(2))))xx`
D. None of these
