A body executes SHM under the influence of one force and has time period 'T_1' seconds. The same body executes SHM with period 'T_2' seconds when under the influence of another force. When both forces act simultaneously and in the same direction then the time period of the same body is

`(T_1 + T_2)` sec

`sqrt(T_1^2 + T_2^2)` sec

`sqrt((T_1 + T_2)/(T_1T_2))` sec

`sqrt((T_1^2 + T_2^2)/((T_1^2 + T_2^2))) ` sec

A body executes SHM under the influence to one force and has time period .T_(1). seconds and the same body executes SHM with period .T_(2). seconds when under the influence of another force. When both forces act simultaneously and in the same direction then the time period of the same body is

`(T_(1) + T_(2))sec`

`sqrt(T_(1)^(2) + T_(2)^(2))sec`

`sqrt((T_(1) + T_(2))/(T_(1)T_(2))) sec`

`sqrt((T_(1)^(2)T_(2)^(2))/((T_(1)^(2) + T_(2)^(2))))`

A body executes SHM under the influence to one force and has time period " T_(1) " seconds and the same body executes SHM with period . T_2 . seconds when under the influence of another force. When both forces act simultaneously and in the same direction then the time period of the same body is:

`(T_(1)+T_(2))`sec

`sqrt(T_(1)^(2) + T_(2)^(2))` sec

`sqrt((T_(1) + T_(2))/(T_(1)T_(2))sec`

`sqrt((T_(1)^(2)T_(2)^(2))/((T_(1)^(2) + T_(2)^(2)))`
