Question
PQ is an infinite current carrying conductor. AB and CD are smooth conducting rods on which a conductor EF moves with constant velocity V as shown. The force needed to maintain constant speed of EF is -
Options
A.
B.
C.
D.
Solution
e = Bvl ⇒ 
⇒ e =
ln(b / a) ⇒ ii = 
ln(b / a)
Force = Bil = b ⇒
f =
⇒ e =
ln(b / a) ⇒ ii = ln(b / a)Force = Bil = b ⇒
f =
