Q.

Two rods A and B of identical dimensions are at temperature 30°C. If A is heated upto 180°C and B upto T°C, then the new lengths are the same. If the ratio of the coefficients of linear expansion of A and B is 4 : 3, then the value of T is: 

  1. A

    270°C

  2. B

    230°C

  3. C

    250°C

  4. D
