The temperature gradient in a rod of length 75 ~cm is 40^ C / m . If the temperature of cooler end of the rod is 10^ C , then the temperature of hotter end is

Options

  1. A50^ C
  2. B40^ C
  3. C35^ C
  4. D25^ C

Correct answer

B. 40^ C

Step-by-step solution

We know aligned & T _ g = T ₁- T ₂ x & T ₁-10 0 75 =40 aligned Temperature of the hotter end is: aligned & T ₁=(40 0.75)+10 & ~T ₁=40^ C aligned
