The time period of oscillations of a block attached to a spring is `t_(1)`. When the spring is replaced by another spring, the time period of the block is `t_(2)`. If both the springs are connected in series and the block is made to oscillate using the combination, then the time period of the block is

Options

A. `T=t_1+t_2`
B. `T^2=t_1^2+t_2^2`
C. `T^(-1)=t_1^(-1)+t_2^(-1)`
D. `T^(-2)=t_1^(-2)+t_2^(-2)`

Answer

B
