Question

a rod of length 2m slides with a speed of 5m per second on a rectangular conducting frame as shown in figure. there exists a uniform magnetic field of 0.04T perpendicular. if the resistance of the rod 3 omega. the current through the rod is​

Answer 1

Answer:

2/15.

Explanation:

The EMF induced in the rod is e = Blv

                                                      = 0.04*2*5 = 0.4 V.

Here, V= 0.4  , I = ?  ; R = 3 ohms.

Therefore, I = V/R = 2/15.
