A metallic square of loop ABCD of size 15 cm and Resistance 1 ohm is moved at uniform velocity of vm/s in a uniform magnetic field of 2TesIa the field lines being normal to the plane of paper. The loop is connected to an electrical network of customs, each of resistance 2 ohms. Calculate the Speed of the loop, for which 2mA Current fun in loop.

Expert Answer:

The network of resistors shown in the figure is a balanced wheatstone's bridge. Hence, its equivalent resistance R1 is given by,
Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.
As resistance of loop R2=1Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '., hence total resistance R = R1 + R2 = 1 + 2 = 3Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '..
As length of side AB of loop l =15 cm = 0.15 m and B = 2 T and direction of motion v is perpendicular to B as well as l, hence induced emf
