Question

Two conducting rails are connected to a
source of emf and forms an incline as
shown in figure. A rod of mass 50 gm. slide
without friction down the incline through a
vertical magnetic field. The value of B so
the rod will slide at a constant velocity (g =
10m/sec2):
v=const.
2.5A

Answer 1

Answer:(g=10m/sec2)

Explanation:

Two conducting rails are connected to a source of e.m.f. and form an incline as shown in the figure. A bar of mass 50g

slides without friction down the incline through a vertical magnetic field B

. If the length of the bar is 50cm

and a current of 2.5A

is provided by the battery, for what value of B

will the bar slide at a constant velocity ? (g=10m/sec2)
