Three rods made of same material and having the same cross-section have been joined as shown. In the figure.Each rod is of the same length. The left and right ends are kept at `0^@C and 90^@C` respectively. The temperature of the junction of the three rods will be

Three rods made of the same material and having the same cross-section have been joined as shown in the figure. Each rod is of the same length. The left and right ends are kept at 0^@C and 90^@C , respectively. The temperature of junction of the three rods will be (a) 45^@C (b) 60^@C (c) 30^@C (d) 20^@C .

Three rods made of same material and having the same cross-section have been joined as shown in fig. each rod is of the same length. The left and the right ends are kept at 0^(@)C and 90^(@)C respectively. What will be the temperature of the junction of the three rods?

Three rods made of same material and having same cross-section have been joined as shown in Fig. 7(e).18. Each rod is of the same length. The left and the right ends are kept at 0^(@)C and 60^(@)C respectively. What is the temperature of the junction of the three rods.

Three rods are made from the same material and having the same cross-sectional area and length have been joined as shown in the figure. The left end and right end are kept 0^@C and 100^@C , respectively . The temperature of the junction of three rods will be

Three rods AB,BC and BD made of the same materical and having the same area of cross section have been joined as shown is the The ends A,C and D are held at temperatures 20^(@)C Cand 80^(@)C respectively If each rod is of same length then find the temperature at the junction B of the three rods .

Two rods of similar area of cross section and length are joined as shown in the figure. The ratio of their thermal conductivity is 2:3. The free ends are maintained at 100^(@)C and 0^(@)C respectivley. THE temperature at junction in steady state is

Three rods made of the same materail and having same cross-section area but diferent length 10 cm, 20 cm and 30 cm are joined as shown. The temperature of the junction is

Five identical rods are joined as shown in figure. Point A and C are maintained at temperature 120° C and 20° C respectively. The temperature of junction B will be

Three thin uniform rods made of same material are joined as shown. Locate c.m .
