Answer Text

Solution :

The displacement of rod AB is increased due to magnetic force exerted on it, if : <br> (i) If the current in the rod is increased then rod will be deflected with greater force. <br> (ii) If a stronger horse-shoe magnet is used then also rod will be deflected with greater force due to the increase in magnetic field. <br> (iii) If the length of the rod AB is increased.

Assertion A metallic rod is fixed from two ends as shown in figure. When the temperature is increased compressive stresses are developed in the rod. <br> <img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/ARH_NEET_PHY_OBJ_V01_C14_E01_133_Q01.png" width="80%"> <br> Reason At higher temperature, natural length of the rod will be more.

Temperature difference of `120^(@)C` is maintained between two ends of a uniform rod AB of length 2L. Another bent rod PQ, of same cross-section as AB and length`(3L)/(2)`, is connected across AB (See figure). In steady state, temperature difference between P and Q will be close to : <br> <img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/JMA_2019_PC_IEH_09_JAN_I_E01_012_Q01.png" width="80%">
