Two identical rods are connected between two containers on of tehm is at 100^@C and another is at 0^@C. If rods are connected in parralel them the rate of melting of ice is q_1 gm//sec. If they are connected in series then the rate is q_2. The ratio q_2//q_1 is

Two identical rods are connected between two containers. One of them is at 100^(@)C containing water and another is at 0^(@)C containing ice. If rods are connected in parallel then the rate of melting of ice is q_(1)g//s . If they are connected in series then teh rate is q_(2)g//s . The ratio q_(2)//q_(1) is

Two identical rods are connected in parallel. One end of the rods is maintained at 100^(@)C and other end is kept in 0^(@)C ice . The rate at which the ice melts is Q_(1) gm/sec . Now the rods are connected in series . The ends are again maintained at 100^(@) C and kept in 0^(@)C ice . Now the rate at which ice melts is Q_(2) gm/sec . Then Q_(2) //Q_(1) is
