Read the following paragraph and answer the questions given below: According to Maxwell distribution, the area under the curve is equal to the total number of molecules in collision. On increasing temperature, fraction of molecules having speed equal to ump (most probable speed) decreases. The speed distribution also depends on the mass of the molecules along with the temperature. In general, the distribution depends upon the value of (M)/(T) (where M is molar mass and T is temperature in kelvin). Choose the correct option: If U_(mp)" at "T_(1) K" is "U_(1), then value of U_(rms)" at "T_(2) is
