A body executes $SHM$ under the influence of one force and has a period $T_1\, second$ and the same body executes $SHM$ with period $T_2\, second$ when under the influence of another force. When bothforces act simultaneously and in the same direction, then the time period of the same body is
  • A$\left( {{T_1} + {T_2}} \right)\,\sec $
  • B$\sqrt {T_1^2 + T_2^2} \,\sec $
  • C$\frac{{\sqrt {T_1^2 + T_2^2} }}{{{T_1}{T_2}}}\,\sec $
  • D$\frac{{{T_1}{T_2}}}{{\sqrt {\left( {T_1^2 + T_2^2} \right)} }}\,\sec $
