The ends of copper rod of length 1 m and area of cross section 1cm^(2) are maintained, at 0^(0)C and 100^(0)C, and steady state achieved. At the centre of rod, there is a source of heat of 25W. The thermal conductivity of copper is 400W/mK

The ends of copper rod of length 1 m and area of cross section 1cm^(2)

1.	The ends of copper rod of length 1 m and area of cross section 1cm^(2) are maintained, at 0^(0)C and 100^(0)C, and steady state achieved. At the centre of rod, there is a source of heat of 25W. The thermal conductivity of copper is 400W/mK
Answer» The temperature GRADIENT in right HALF is `412^(0)C//m` The temperature gradient in left is `212^(0)C//m` The temperature of rod at centre is `206^(0)C` The temperature of rod at centre is `50^(0)C` Answer :A::B::C
