A rod of 30cm length has its ends P and Q kept 20 C and 80 C respectively until steady state condition prevail. The temperature at each point end is suddenly reduced to 0 C and kept so. Find the conditions for solving the equation. |
| A. | u(0,t) = 0 = u(30,t) and u(x,0) = 20 + 60/10 x |
| B. | u<sub>x</sub>(0,t) = 0 = u<sub>x</sub>(30,t) and u(x,0) = 20 + 60/30 x |
| C. | u<sub>t</sub>(0,t) = 0 = u<sub>t</sub>(30,t) and u(x,0) = 20 + 60/10 x |
| D. | u(0,t) = 0 = u(30,t) and u(x,0) = 20 + 60/30 x |
