A bimetallic strip made of aluminum and ...

A bimetallic strip made of aluminum and steel `(alpha_(Al) gt alpha_(steel))` on heating the strip will a) remain straight b) get twisted c) will bend with aluminum on concave side d) will bend with steel on concave side.

A

remain straight

B

get twisted

C

will bend with aluminium on concave side

D

will bend with steel on concave side.

Text Solution

Verified by Experts

The correct Answer is:
D
Since `alpha_(al) gt alpha_("steel")` so on heating the bimetallic strip, aluminium strip will expand more than that of steel strip.
Due to it, steel strip will bend on concave side.

A currrent I is passed through a silver strip of width d and area of cross section A. The number of free electrons per unit volume is n. (a) Find the drift velocity v of the electrons. (b) If a magnetic field B exists in the region as shown in what is the average magnetic force on the free electrons? (c) Due to the magnetic force, the free electrons get accumulated on one side of the conductor along its length. This produces a transverse electric field in the conductor which opposes the magnetic force on the electrons. Find the magnitude of the electric field which will be the potential diference developed across the width of the conductor due to the electron- accumulation? The appearance of a transverse emf, when a current-carrying wire is placed in a magnetic field, is called hall effect.
